21 Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

Ecclesiastes 7:22

22 For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

Ecclesiastes 10:10

10 If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.

Ecclesiastes 10:20

20 Curse not the king, no not in thy thought; and curse not the rich in thy bedchamber: for a bird of the air shall carry the voice, and that which hath wings shall tell the matter.
