Thomas Aquinas, on Ps 19:6

“We will rejoice in thy salvation; and in the name of our God we shall be exalted.”

“"Now I know." Here the hope of being heard is set forth, and he says: considering that from your good we shall be multiplied, "now I know that the Lord has saved his Christ"; so that it may be understood either of Christ, through whom many have been saved, or of David, whom he saved by predestination. "Now," as if "from now" before it happens: 1 Pet. 1: "Concerning which salvation the prophets inquired, foretelling the sufferings that are in Christ, and the subsequent glories." And not only is it that he has saved Christ Jesus by raising him from the dead -- Ps. 15: "You will not give your holy one to see corruption" -- and so, with the head saved, the members shall be saved; but "he will hear him," namely Christ praying for his members: Jn. 11: "Father, I know that you always hear me." Or David. "He will hear." Here the power of the one who hears is commended. And first he sets forth the power. Second, the proof of the power, at "Some trust in chariots." "Might" denotes a multitude of power. Might is the vigorous work of a ruler. And it can be referred to men, so that the sense is: the salvation of your right hand, by which you save Christ and us through him, appears in mighty deeds, that is, in every place where he acts powerfully and mightily in us. Or it can be referred to God: and so, "the salvation of your right hand is in mighty deeds," that is, in the greatness of your power: Ps. 67: "Who brings forth the bound in strength." And he says "of the right hand," because there is a twofold salvation of God. One, namely, of the left hand, by which he saves in temporal things, bestowing temporal goods: Ps. 48: "Men and beasts you will save, O Lord." The other is the salvation of the right hand, which is of eternal things, by which he saves the just, bestowing gifts: Wis. 10: "God repaid the reward of the labors of his saints."”
