John Trapp on Proverbs 19:2

Verſ. 2. Alſo that the ſoul bee without knowledge, Lib. 3. Eth. it is not good] An ignorant man is a naughty man. Ignorat ſanè improbus omnis, ſaith Ariſtotle. Every bad-minded man is in the dark; neither can any good come into the heart, but it muſt paſs through the underſtanding; and the difference of ſtature in Chriſtianity grows from different degrees of knowledge. The Romans were full of knowledge, and therefore full of goodneſs, chap. 15.14.

And hee that haſteth with his feet ſinneth] Or, wandreth out of the way. As hee that is out of his way, the faſter hee rides or runs, the farther hee is out; ſo is blinde zeal. It is like metal in a blind horſe, that running upon the rocks and precipices firſt breaks his hoofs, and then his neck: Or like the Devil in the poſſeſſed, that caſt him ſometimes into the fire, and ſometimes into the water.
