Psalm 90 v1 - Trust in God, the Most High

Qui hábitat in adjutório Altíssimi, in protectióne Dei cæli commorábitur.

He that dwells in the aid of the most High, shall abide under the protection of the God of Jacob.

The first lesson in the spiritual warfare set out in Psalm 90 is that we must put out trust in God: not just momentarily, in times of trouble; but by consistently and actively cultivating a constant awareness of his abiding presence.

Understanding the Latin

The key vocabulary for the verse is:

habito, avi, atum, are  to dwell, abide, live.

adjutorium i n – help, aid ,assistance; shield; hiding place, shelter, protection; prop, support;
altissimus i m the Most High

protectio – onis f covering, protection
caelum, i, n., or caeli, orum, m.  heaven, the abode of God; the heavens as opposed to the earth; the air; 

commoror, atus sum, ari, to dwell, abide.

Taking it word by word then: 

Qui (who) hábitat (he lives) in (with, in) adjutório (the help) altíssimi (of the highest, most high), in (with, under) protectióne (the protection) dei (of the God) cæli (of heaven) commorábitur (he will dwell)

It is worth noting that the Latin translators of this verse have taken often quite different approaches to each other, as the table below illustrates:

	VULGATE	Qui hábitat in adjutório altíssimi, * in protectióne Dei cæli commorábitur.
	Neo-Vulgate	Qui habitat in protectione Altissimi, sub umbra Omnipotentis commorabitur.
	Pian	Qui regis in praesidio Altissimi, Qui sub umbra Omnipotentis commoraris,
	Jerome from the Hebrew	Qui habitat in abscondito Excelsi, in umbraculo Domini commorabitur.
	(Septuagint	ὁ κατοικῶν ἐν βοηθείᾳ τοῦ ὑψίστου ἐν σκέπῃ τοῦ θεοῦ τοῦ οὐρανοῦ αὐλισθήσεται)

Our trust is in God, the creator and sustainer of all things

Psalm 90 opens with words that stress just who it is we are being instructed to place our hope in, namely the God who dwells in heaven, Christ enthroned in glory.

The two words for God here (Altissimi and Dei) actually stand for two of the most ancient names of God,  עֶלְיוֹן (elyown, Most High) and שַׁדַּי (shadday), adding a sense of extra solemnity to the verse.

The promise of God's aid

It then provides an assurance that God will always protect us the just.   

But there is a precondition for his help: for the promise to apply, the verse implies that we must put all our trust in God.

And the trust we place in God cannot be a mere momentary thing, but rather we must ‘dwell’ constantly in his will.  St Robert Bellarmine here notes that: 

his liberal promise does not apply to those who put only a certain amount of trust in God, but that this trust must be continuous, constant, and firm, so that man may be said to dwell in God, through faith and confidence, and to carry it about with him, like a house…

God helps those who help themselves

As its Scriptural usage in the New Testament attests (see for example in St Matthew 4), this verse is not an invitation to put ourselves needlessly in harm's way in the expectation that God will save us.

Nor is it an invitation to passivity.

Dwelling with the aid of God, the wording of the Vulgate text, implies something of the real effort we must put in to truly do God’s will.

In this it stands in contrast to the neo-Vulgate, which, following the Hebrew Masoretic Text, changed  in adjutorio (help or aid) in the first phrase to ‘in protectione’ (covering, protection), and the in protectione of the second phrase into ‘sub umbra’ (under the shadow, in the shelter of), giving it a more passive sense of the text than the Septuagint/Vulgate tradition.

Yet the more active sense of the Vulgate, I think, reflects the tradition better, since as St Robert Bellarmine comments: 

…we are not to neglect the ordinary means that man can avail himself of. The husbandman puts his trust in him who gives the rain from heaven, and makes his sun to rise, but in the meantime he will be sure to plough, to sow, and to reap, knowing that God helps those who help themselves.
