Cease, my son, to hear the instruction that causeth to err from the words of knowledge.
– Proverbs 19:27
The wording presents difficulties in this proverb and commentators take it variously. The word for understanding means discipline, or correction. Without any modifiers, the word is positive in Proverbs. It is the good discipline and correction of wisdom. So it is not the instruction that causes to go astray, but rather the refusal to hear and heed instruction that causes to go astray. It is akin to the admonition in Proverbs 14:7. The words of knowledge lay down a good way to go. One must hear the words of knowledge and walk in them (Proverbs 3:18; 4:4, 13; 15:24).
