Matthew Henry on Proverbs 1:7-9

Fools are persons who have no true wisdom, who follow their own devices, without regard to reason, or reverence for God. Children are reasonable creatures, and when we tell them what they must do, we must tell them why. But they are corrupt and wilful, therefore with the instruction there is need of a law. Let Divine truths and commands be to us most honourable; let us value them, and then they shall be so to us.
