Proverbs 29:19-21 21st Century King James Version (KJ21)
19 A servant will not be corrected by words; for though he understand, he will not give heed.
20 Seest thou a man that is hasty in his words? There is more hope for a fool than for him.
21 He that delicately bringeth up his servant from childhood shall have him become his son in the end.
