¹⁵ The rod and reproof give wisdom;
But a child left to himself causeth shame to his mother.

¹⁷ Correct thy son, and he will give thee rest;
Yea, he will give delight unto thy soul.

¹⁹ A servant will not be corrected by words;
For though he understand, he will not ^[a]give heed.

²¹ He that delicately bringeth up his servant from a child
Shall have him become ^[a]a son at the last.
