Albert Barnes Commentary Proverbs 19:27

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

Literally, Cease, my son, to hear instruction, that you may err from the words of knowledge; this is advice given ironically to do that to which his weakness leads him, with a clear knowledge of the evil to which he is drifting.
