John Trapp on Psalms 12:7

Verſ. 7. Thou ſhalt keep them] that is, Verba praedicta, the forementioned words or promiſes, ſaith Aben-Ezra. Or, keep thou them (prayerwiſe,) and ſo David puts Gods promiſes in ſuit. A certain good man having all taken from him, and his Wife deſiring to know how hee and his Family ſhould live? He anſwered, hee would now put his Bond in ſute; that is, he would urge God with his Promiſes.

Thou ſhalt preſerve them] Heb. Him, that is, every one of them, viz. the poor and needy, amongſt whom David reckons himſelf, which ſhews his humility.

From this Generation] So they are called for their multitude, in oppoſition to thoſe few faithful ones, verſ. 1. An evil and adulterous Generation they were, a Baſtardly brood, as Mat. 12.39. Omne tempus feret Clodios, Catones non omne feret, ſaith Seneca.
