Proverbs 10:26; Proverbs 25:19; Proverbs 30:14

26 As vinegar to the teeth, and as smoke to the eyes, so is the sluggard to them that send him.

19 Confidence in an unfaithful man in time of trouble is like a broken tooth, and a foot out of joint.

14 There is a generation, whose teeth are as swords, and their jaw teeth as knives, to devour the poor from off the earth, and the needy from among men.
