Ps 19:8

“"They have been bound, and fallen" [Psalm 20:8]. And therefore were they bound by the lust of temporal things, fearing to spare the Lord, lest they should lose their place by "the Romans:" [John 11:48] and rushing violently on the stone of offense and rock of stumbling, they fell from the heavenly hope: to whom the blindness in part of Israel has happened, being ignorant of God's righteousness, and wishing to establish their own. "But we are risen, and stand upright." But we, that the Gentile people might enter in, out of the stones raised up as children to Abraham, [Matthew 3:9] who followed not after righteousness, have attained to it, and are risen; [Romans 9:30] and not by our own strength, but being justified by faith, we stand upright.”

“These trust in chariots Some nations trust in their iron chariots, and some trust in horses, but we pray in the name of the Lord, because the salvation is His. נזכיר is an expression of burning sacrifices and of prayer, as (in Isa. 66:3): “he who burns (מזכיר) frankincense,” (and in Lev. 2:2): “its memorial part (אזכרתה).” Therefore, they kneel and fall...”

“Call upon. Septuagint Roman, Syriac, &c., read, “we shall be exalted,” megalunthesometha , (Calmet) as [in] ver. 6. Some call upon or trust in chariots, &c. (Haydock) — Hebrew, “remember,” which often implies to confide, (Calmet) and such we call upon as we hope will be able and willing (Haydock) to protect us. (Berthier) — Let our enemies assemble all their forces and auxiliaries, we shall not fear as long as God is for us. (Calmet) — The Jewish kings were forbidden to multiply horses, that they might not be tempted to confide in them. (Haydock)”
