Thomas Aquinas, on Ps 19:7

“The Lord fulfill all thy petitions: now have I known that the Lord hath saved his anointed. He will hear him from his holy heaven: the salvation of his right hand is in powers.”

“Consequently he sets forth the proof of this power. And first he sets forth the diversity of trust and glory among men. Second he sets forth the outcome for both, at "They have been bound." For there is a twofold kind of men. Some place all their hope in secular power: against whom it is said, Jer. 17: "Cursed is the man who trusts in man": Ps. 51: "The just shall see and shall laugh, and shall say," etc. Others place their hope in God: Ps. 117: "It is good to trust in the Lord." And therefore he says, "Some trust in chariots and some in horses"; as if to say: some trust in secular power, of whom it is said, "Some trust in chariots," etc. Or it refers to battle or to triumphs; because some fight in chariots and some on horses: Ex. 15: "Pharaoh entered with chariots and horsemen." Or it refers to triumphs, and then they do not trust but glory: because according to the Gloss, in ancient times there was a twofold kind of triumph -- one greater, the other lesser. The first was called "laureate," because the victor was crowned with laurel; and this was done in a chariot. The second was called an "ovation"; and it was done on horseback. As if to say: some glory in great things, some in horses, as in an ovation. "Ovo, ovas" means the same as "to rejoice"; and it is derived from boys who rejoice when they are given an egg. But we in great things -- that is, we glory "in the name of the Lord." A triumph is called from "tris," which is "three," and "phonos," which is "sound"; because a triple sound was exhibited to returning victors. First, the whole people went out to meet him. Second, all the captives followed his chariot with bound hands. Third, he himself, clothed in the tunic of Jupiter, sat in a chariot drawn by four white horses; and so he was led to the Capitol. But in the chariot with him was placed a certain servant, who slapped him saying, "Know yourself."”
