• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Proverbs 19:27: Pro 19:27 27 Cease, my son, to hear instruction, To depart from the words of knowledge. Oetinger correctly: cease from hearing instruction if thou wilt make no other use of it than to depart, etc., i.e., cease to learn wisdom and afterwards to misuse it.
