Psalm 129: Verses 1-2

El Greco The Repentance of St Peter

The first two verses of Psalm 129 above all justify its inclusion as one of the Seven Penitential Psalms.  But they also have other lessons to offer us on the nature of prayer in general.

Notes on the verses

1	V/NV/JH*	De profúndis clamávi ad te, Dómine: * Dómine, exáudi vocem meam :
	Sept	ἐκ βαθέων ἐκέκραξά σε κύριε κύριε εἰσάκουσον τῆς φωνῆς μου

De (from/out of) profúndis (the deeps) clamávi (I have called) ad (to) te (you) Dómine (O Lord) Dómine (O Lord) exáudi (hear) vocem (the voice) meam (my)

The depths (profundis) can mean literally the depths of the sea, or the depths of misfortune and sin. The Monastic Diurnal's translation, along the RSV, makes this verse present tense to reflect the Hebrew perfect (action occurring simultaneously).   

profundum, i, n., the depth, the sea, any deep water;  the depths, deep

clamo, avi, atum, are  to call, cry out; to call to or upon for aid.

exaudio, ivi, Itum, ire, to hear, hearken to, listen to, give heed to; to regard, answer

vox, vocis, f., the voice of a person, or, the sound of an instrument, thunder. 

DR	Out of the depths I have cried to you, O Lord: I have cried to you, Lord, hear my voice.
Brenton	Out of the depths have I cried to thee, O Lord. 2 O Lord, hearken to my voice
Cover	Out of the deep have I called unto thee, O Lord; Lord, hear my voice.
KJV 1769	Out of the depths have I cried unto thee, O LORD.

To obtain God's mercy, according to this verse, requires two things: intensity in prayer (a cry) and a recognition of the depths of our sin.  the Catechism of the Catholic Church (2559) notes that:

"Prayer is the raising of one's mind and heart to God or the requesting of good things from God." But when we pray, do we speak from the height of our pride and will, or "out of the depths" of a humble and contrite heart? He who humbles himself will be exalted; humility is the foundation of prayer, Only when we humbly acknowledge that "we do not know how to pray as we ought," are we ready to receive freely the gift of prayer. "Man is a beggar before God."

The Fathers' commentaries on this verse point us to examples of great sinners who repented deeply, such as Jonah in the whale, St Peter, and the tax-collector.

2	V/NV	Fiant aures tuæ intendéntes: * in vocem deprecatiónis meæ.
	JH	fiant aures tuae intendentes ad uocem deprecationis meae.
	Sept	γενηθήτω τὰ ὦτά σου προσέχοντα εἰς τὴν φωνὴν τῆς δεήσεώς μου

Fiant (let them be) aures (the ears) tuae (your) intendéntes (being attentive = be attentive) in vocem (to the voice) deprecatiónis (supplications) meæ (my supplications)

The Coverdale translation renders the last phrase as 'the voice of my complaint', but 'complaint' here is really meant in the Old English sense of a petition or request for mercy or pardon.

fio, factus sum, fieri , to be made or done, to become, happen

auris, is, f the ear.

intendo, tendi, tentum, ere 3 to give heed to, pay attention to.

vox, vocis, f., the voice of a person, or, the sound of an instrument, thunder. 

deprecatio, onis, prayer, supplication, entreaty.

DR	Let your ears be attentive to the voice of my supplication.
Brenton	let thine ears be attentive to the voice of my supplication.
Cover	O let thine ears consider well the voice of my complaint.
KJV	Lord, hear my voice: let thine ears be attentive to the voice of my supplications

Prayer is communication between two people.  The opening verse demands that we say 'I', that we acknowledge our sin individually.  This verse turns to the other side of the conversation, namely God, and  asks that he listens to us.  Yet since God sees and hears everything anyway, why do we need to do that?  First we need to be clear that we are not just talking to ourselves but seeking to engage directly with our creator and redeemer!  Secondly, we do need to be insistent when we really want something.  St Robert Bellarmine comments:

"However loud one may cry, he will not be heard, unless the person to whom he cries attend to him. People are often so absorbed in other mat­ters, that they pay no heed to one talking to them, and then one talks to them in vain. Now, God always sees and hears every­thing, but when he does not grant what we ask, he is like one that does not attend to us, as if he were thinking of something else, and, therefore, David, being most anxious for a hearing, and not content with having called out with a loud voice, asks, furthermore, that God may deign to attend to him; that is, to receive his prayer, and grant what it asked."

Psalm 129: De Profundis - Introduction

The first psalm of Tuesday Vespers, Psalm 129, is a psalm that is used in many different contexts: it is one of the seven penitential psalms; it is used in the Office of the Dead at Vespers; it is a traditional preparatory prayer for Mass; and it carries an indulgence if said for those in purgatory.

Historical context

The psalm is almost certainly Davidic in origin, as 2 Chronicles 6:36-42, which is part of a prayer of King Solomon, alludes to and explains this psalm, and explicitly mentions Solomon's father, King David in this context.

Here are the verses in question from Chronicles:

"And if they sin against you (for there is no man that sins not) and you be angry with them, and deliver them up to their enemies, and they lead them away captive to a land either afar off, or near at hand, and if they be converted in their heart in the land to which they were led captive, and do penance, and pray to you in the land of their captivity saying: We have sinned, we have done wickedly, we have dealt unjustly: And return to you with all their heart, and with all their soul, in the land of their captivity, to which they were led away, and adore you towards the way of their own land which you gave their fathers, and of the city, which you have chosen, and the house which I have built to your name: Then hear from heaven, that is, from your firm dwelling place, their prayers, and do judgment, and forgive your people, although they have sinned: For you are my God: let your eyes, I beseech you, be open, and let your ears be attentive to the prayer, that is made in this place. Now therefore arise, O Lord God, into your resting place, you and the ark of your strength: let your priests, O Lord God, put on salvation, and your saints rejoice in good things. O Lord God, turn not away the face of your anointed: remember the mercies of David your servant."

In the Benedictine Office

Above all though, it is one of the Gradual psalms, the pilgrim songs sung as the pilgrims climbed the steps to the Temple on the occasion of the great feasts each year.  The slow ascent of the steps is meant to symbolize the pilgrim's journey, firstly towards the earthly Temple, but also the spiritual ascent to heaven.

Christ's earthly life, and particularly his public ministry which we can particularly meditate today on, in the context of the Office, is meant to teach us how to make that spiritual ascent: following the steps of the Apostles as they learnt from the Master, we too can gradually grow in the grace represented by each of these steps.

In this light, Pope Benedict XVI suggested that:

"the text is first and foremost a hymn to divine mercy and to the reconciliation between the sinner and the Lord, a God who is just but always prepared to show himself "a merciful and gracious God, slow to anger and rich in kindness and fidelity, continuing his kindness for a thousand generations, and forgiving wickedness and crime and sin" (Ex 34: 6-7)."

One can perhaps use it to meditate on incidents in the Gospel such as Jesus' repeated forgiveness of sins of those he healed through his miracles; the tearful repentance of Mary Magdalene; the story of the woman caught in adultery and more.

Competing textual traditions?

It is worth noting that this is one of those psalms where the Septuagint Greek (and thus Vulgate) and the (late medieval) Hebrew Masoretic Text are in places very different, in ways impossible to reconcile by looking for alternative readings of the Hebrew.  

In particular, from verse 4 onwards, the Hebrew puts much more emphasis on fear of God, and omits two references to the hope of the Christ’s redemption.  This may well be the result of early rabbinical reaction to Christianity, and in fact the text is so corrupt that in places even protestant bibles that usually prefer the Hebrew have adopted the Vulgate tradition.

Tuesday in the Benedictine Office

St Mary's Church, Lewisham, UK

I'm currently running a series on the psalms of Vespers, and we have now reached Tuesday at that hour. Before looking at the individual psalms of Tuesday Vespers, though, I thought it might be helpful first to consider the context of the Office of Tuesday as a whole.

The public ministry of Christ, the true Temple

Monday in the Benedictine Office, I've previously suggested, can be seen as a meditation on the life of Christ from his birth to baptism and temptation in the desert.

Tuesday, I want to suggest, is an appropriate time to meditate on the public ministry of Christ, and particularly the growth in the spiritual life and holiness that comes from the imitation of Christ, as we stand in the footsteps of the disciples, hearing his preaching.  In fact, the first very first psalm of Matins, Psalm 45, supports that idea quite nicely, asserting that 'God is in the midst of us',  'doing wonders on the earth' (Deus in médio ejus… Veníte, et vidéte ópera Dómini, quæ pósuit prodígia super terram).

Above all though, the day's key theme is, I think, Christ as the true Temple.

The psalms of Matins and Lauds are full of references to the city of God, the heavenly temple, psalms which Christians have long interpreted as being about the desire for Christ himself.  Indeed, Psalm 42, which is said at Lauds, forms the basis of the prayers at the foot of the altar in the traditional Mass.

Gradual Day

One of the most distinctive features of the Benedictine Office, though, is the use of nine of the Gradual Psalms at Terce to None from Tuesday to Saturday (the older form of the Roman Office used Psalm 118 at these hours).

And on Tuesday, St Benedict goes further, arranging it so that all of the 'psalms of ascent' (Psalms 119-133), save for Psalm 128 (said on Monday) are said in order.

These psalms are thought to have been sung liturgically as the pilgrims ascended the fifteen steps of the Temple in Jerusalem on major feasts.  

These psalms can also be viewed as pilgrim songs, appropriate perhaps for Christ's wanderings around the region as he preached.  

But above all, the Fathers saw them as tracing the mystical ascent of the Christian in the spiritual life in imitation of Christ, who shows us how to climb Jacob’s ladder to heaven and grow in virtue.

The first of the group, Psalm 119, presents us with the image of an exile, a stranger living amongst antagonistic peoples, who has ‘lived too long in exile’.  Hebrews 11 nicely summarises the story line that then develops:

“These all died in faith…having acknowledged that they were strangers and exiles on the earth. For people who speak thus make it clear that they are seeking a homeland. If they had been thinking of that land from which they had gone out, they would have had opportunity to return. But as it is, they desire a better country, that is, a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared for them a city.”

Hebrews contrasts the story of the Old Testament figures who set out on this journey, but were not able to arrive at the destination because heaven was closed to them by Original Sin, with our situation, whereby the gates to heaven have been reopened by our Lord. But it also points to the key orientation of the Christian: living in the world, but not being of it; and focusing on laying up treasure in heaven, not in the here and now:

"Why then, since we are watched from above by such a cloud of witnesses, let us rid ourselves of all that weighs us down, of the sinful habit that clings so closely, and run, with all endurance, the race for which we are entered. Let us fix our eyes on Jesus, the origin and the crown of all faith, who, to win his prize of blessedness, endured the cross and made light of its shame, Jesus, who now sits on the right of God’s throne." (Hebrews 12)


Indeed, Christ is the 'third temple', as St John's Gospel asserts in a text that many of the Fathers regarded as the key to the interpretation to the Gradual psalms:

"Jesus answered them, Destroy this temple, and in three days I will raise it up again. At which the Jews said, This temple took forty-six years to build; wilt thou raise it up in three days? But the temple he was speaking of was his own body; and when he had risen from the dead his disciples remembered his saying this, and learned to believe in the scriptures, and in the words Jesus had spoken." (John 2: 19-22).

Vespers on Tuesday

Vespers on Tuesday features four of the gradual psalms, Psalms 129-132.  Two of these (Psalms 130 and 132) are very short indeed - only three verses as they appear in Scripture, though lengthened somewhat in their liturgical presentation.   

There is, arguably, a particular logic to the split between the gradual psalms used at the little hours and those at Vespers: Cassiodorus, St Benedict’s contemporary, suggests that the first nine of the group refer to our life on earth, while the next group look to heaven.

But there is perhaps a deeper logic to them in terms of their specific content and Christ's message to us:

• Psalm 129, De Profundis, is a hymn to God's saving mercy, for God looks not at our sins and merits but instead redeems us through his mercy;
• Psalm 130, Domine non est exaltatum cor meum, urges us to meditate on the necessity of humility, which Christ taught us by his willingness to take human form and die a dreadful death;
• Psalm 131, Memento Domine David, can be interpreted as an ode to the Real Presence and the importance of worship; and 
• Psalm 132, Ecce quam bonum praises the unity of community life, urging us to love and serve one another.

Psalm 128 (129) – Saepe expugnaverunt me

Vulgate	Douay-Rheims
Canticum graduum.	A gradual canticle.
1 Sæpe expugnavérunt me a juventúte mea, * dicat nunc Israël:	Often have they fought against me from my youth, let Israel now say.
2  Sæpe expugnavérunt me a juventúte mea: * étenim non potuérunt mihi.	2 Often have they fought against me from my youth: but they could not prevail over me.
3  Supra dorsum meum fabricavérunt peccatóres: * prolongavérunt iniquitátem suam.	3 The wicked have wrought upon my back: they have lengthened their iniquity.
4  Dóminus justus concídit cervíces peccatórum: * confundántur et convertántur retrórsum omnes, qui odérunt Sion.	4 The Lord who is just will cut the necks of sinners: 5 Let them all be confounded and turned back that hate Sion.
5  Fiant sicut fœnum tectórum: * quod priúsquam evellátur exáruit:	6 Let them be as grass upon the tops of houses: which withers before it be plucked up:
6  De quo non implévit manum suam qui metit: * et sinum suum qui manípulos cólligit.	7 Who with the mower fills not his hand: nor he that gathers sheaves his bosom.
7  Et non dixérunt qui præteríbant: Benedíctio Dómini super vos: * benedíximus vobis in nómine Dómini.	8 And they that passed by have not said: The blessing of the Lord be upon you: we have blessed you in the name of the Lord.

Notes on the verse

7. Et non dixerunt qui præteribant: Benedictio Domini super vos. Benediximus vobis in nomine Domini.

And they that have passed by have not said: The blessing of the Lord be upon you: we have blessed you in the name of the Lord.

Et (and) non (not) dixérunt (they have said) qui (who) præteríbant (they pass by) benedíctio (the blessing) Dómini (of the Lord) super (on/over) vos (you) benedíximus (we have blessed) vobis (you) in nómine (in the name) Dómini (of the Lord)

praetereo, li, ltum, ire,  Of place: to go by, pass by.

benedictio, onis, /.a blessing.

benedico, dixi, dictum, ere 3  to bless, to praise, bless, give thanks to (God);  to be well pleased with, to take pleasure in

nomen, mis, n. name

Cassiodorus explains the context of the blessing being denied:

It was a custom among the Jews that if passers-by came upon individuals working at some agricultural task, they bestowed grace and a blessing on them. So we read in the book of Ruth: And Booz said to the young man that was set over the reapers, The Lord be with you: and they answered him, The Lord bless thee. Here an implication contrary to this custom is assumed, for no blessing is bestowed on wicked men who work to no effect. 

St Augustine points out that those who reject Christ are owed no blessings, but rather condemnation. Because we are friends of the bridegroom, he argues, we must 'refuse to be adulterers of the bride'.

And that brings to an end our consideration of the psalms of Monday Vespers.  You can find an overview of Tuesday in the Benedictine Office here.

Psalm 128 verses 5-6

Today's verses of Psalm 128 take the form of a curse on the face of it, and so need to be considered in their proper context: these words a warning to repent, for repentance and salvation are always possible while we still have life!

Psalm 128 (129) – Saepe expugnaverunt me

Vulgate	Douay-Rheims
Canticum graduum.	A gradual canticle.
1 Sæpe expugnavérunt me a juventúte mea, * dicat nunc Israël:	Often have they fought against me from my youth, let Israel now say.
2  Sæpe expugnavérunt me a juventúte mea: * étenim non potuérunt mihi.	2 Often have they fought against me from my youth: but they could not prevail over me.
3  Supra dorsum meum fabricavérunt peccatóres: * prolongavérunt iniquitátem suam.	3 The wicked have wrought upon my back: they have lengthened their iniquity.
4  Dóminus justus concídit cervíces peccatórum: * confundántur et convertántur retrórsum omnes, qui odérunt Sion.	4 The Lord who is just will cut the necks of sinners: 5 Let them all be confounded and turned back that hate Sion.
5  Fiant sicut fœnum tectórum: * quod priúsquam evellátur exáruit:	6 Let them be as grass upon the tops of houses: which withers before it be plucked up:
6  De quo non implévit manum suam qui metit: * et sinum suum qui manípulos cólligit.	7 Who with the mower fills not his hand: nor he that gathers sheaves his bosom.
7  Et non dixérunt qui præteríbant: Benedíctio Dómini super vos: * benedíximus vobis in nómine Dómini.	8 And they that passed by have not said: The blessing of the Lord be upon you: we have blessed you in the name of the Lord.

Notes on the verses

5. Fiant sicut fœnum tectorum, quod priusquam evellatur exaruit:Let them be as grass on the tops of houses: which withered before it be plucked up

6. de quo non implevit manum suam qui metit, et sinum suum qui manipulos colligit. 

Wherewith the mower filleth not his hand: nor he that gathereth sheaves his bosom.  

Fiant (let them be) sicut (like) fœnum (grass) tectórum (on the rooftop) quod (that) priúsquam (before)

evellátur (it is pulled out) exáruit (it) withers

The image is of blades of wheat or corn growing on flat roofs that can never develop sufficient roots to harvest because the soil is too shallow and it lacks protection from the sun.

fio, factus sum, fieri (pass, of facio), to be made or done, to become, happen

foenum, i, n., grass.

tectum, i, n.  a roof, house top.

priusquam or prius quam, adv., before, before that.

evello, velli, vulsum, ere 3, to tear, pull, or pluck out.

exaresco, arm, escere 3, to become dry, to wither, dry up. 

De (from) quo (which) non (not) implévit (he does not fill) manum (hand) suam (his) qui (who/which) metit (he reaps et (and) sinum (breast) suum (his) qui (who/which) manípulos (sheaves) cólligit (he gathers)

The second phrase is difficult to translate. ‘Sinus’ normally means bosom or breast – some have suggested that the thought is probably that no bunch of grass is able to be gathered up against his breast in order to be tied into a sheaf.  Others though have suggested that sinus here refers to the fold of a garment where things can be tucked in, and the NETS Septuagint adopts this translation, making the verse 'With which no reaper filled his hand, and a gatherer of sheaves, the fold of his garment'.

impleo, plevi, pletum, ere 2  to fill, fill up, fill full;  to fill, to cover; to fill, satisfy.

manus, us, f.,  hand

meto, messiii, messum, ere 3, to reap, mow, gather harvest.

sinus, us, m.,  bosom, breast; the arm.

colligo, legi, lectum, ere 3 to gather, gather together, collect.

manipulus, i, m.  a small bundle, a handful; a sheaf. 

Isaiah's prophecy about the destruction of Sennacherib (2 Kings 19:26) uses the identical image of grass on a rooftop.  Bellarmine explains the extension of the metaphor:

Another imprecation, which, too, is to be read as a prediction, for it conveys to us the briefness of the happiness of the wicked, and, by a very happy idea, compares it to grass, a vile and fragile substance, and, as is said of it, "which is to day, and tomorrow will be cast into the fire;" and, not content with comparing it to grass, he adds, that it is like the grass that grows on the top of a house, a thing of no value, so much so that nobody ever thinks of cutting it, saving it, or making it into bundles, but leaves it where it grows to wither and to rot. 

He goes on to encourage us to ponder final judgment:

At present, we don't see the full extent of this comparison, though we know of nothing, perhaps, more worthless, or of less value than such grass; but when we shall all come to be judged we shall see that such a comparison, instead of being over the mark, is considerably under it. What will be, then, to see those who abounded in the riches and power of this world, and who imagined they had, through such riches, established themselves and their families in their kingdoms and empires, shoved out ignominiously, and hurled into the lowest pit? and, furthermore, to see those who had reveled in pleasures and enjoyments, who knew not how to put up with the slightest inconvenience, consigned to everlasting torments, without the slightest hope of the smallest relief for all eternity?

And you can find notes on the last verse of the psalm here.

Dóminus (the Lord) justus (just) concídit (he cuts) cervíces (the necks) peccatórum (of sinners)

confundántur (let them be put to shame) et (and) convertántur (let them be converted/turned) retrórsum (back) omnes (all) qui (who) odérunt (hate) Sion

The Septuagint/Vulgate version of this verse suggests that sinners have been punished (their necks cut off); the surviving medieval Hebrew version (reflected in the RSV) gives a rather obscure allusion to ‘cutting the cords’, perhaps to the ploughs (of the foreign invaders?) mentioned in the previous verse.  

The Coverdale translation attempts to make sense of the received Hebrew version as follows: "But the righteous Lord hath hewn the snares of the ungodly in pieces. Let them be confounded and turned backward, as many as have evil will at Sion."

Knox, however, offers perhaps a more PC translation of the sense of the verse: "but the Lord proved faithful, and cut the bonds of tyranny asunder.Let them be dismayed and routed, all these enemies of Sion."

Many of the Fathers and Theologians see this verse as an encouragement to those who are faithful to the Church.  St Robert Bellarmine, for example, summarises the sentiment as: 'cheer up', for eventually God's justice will catch up with the impenitent sinner!  St Augustine, however, approaches the verse as a warning to us all, and that seems to me to fit better with St Benedict's reasons for placing this psalm here:

Which of us does not fix his eyes upon the earth, like the Publican, and say, Lord, be merciful unto me a sinner? Luke 18:13 If therefore all are sinners, and none is found without sin; all must fear the sword that hangs above their neck, because the righteous Lord shall hew the necks of the sinners.
