Matthew Henry's Complete Bible Commentary

Verse 12

Here is, 1. The special care God takes to preserve knowledge, that is, to keep up religion in the world by keeping up among men the knowledge of himself and of good and evil, notwithstanding the corruption of mankind, and the artifices of Satan to blind men’s minds and keep them in ignorance. It is a wonderful instance of the power and goodness of the eyes of the Lord, that is, his watchful providence. He preserves men of knowledge, wise and good men (2 Chronicles 16:9), particularly faithful witnesses, who speak what they know; God protects such, and prospers their counsels. He does by his grace preserve knowledge in such, secures his own work and interest in them. See Proverbs 2:7, 2:8. 2. The just vengeance God takes on those that speak and act against knowledge and against the interests of knowledge and religion in the world: He overthrows the words of the transgressor, and preserves knowledge in spite of him. He defeats all the counsels and designs of false and treacherous men, and turns them to their own confusion. MHBCC 651.12
