Charles Ellicott Commentary Proverbs 19:27

"Cease, my son, to hear instruction [Only] to err from the words of knowledge." — Proverbs 19:27 (ASV)

Cease, my son, to hear the instruction that causes to err... — Or the passage may mean, Cease to hear instruction if you are only going to err afterwards — Make up your mind what you intend to do in the future, and act now accordingly; better not know the truth than learn it only to desert it. (Compare 2 Peter 2:21).
