Proverbs 10:26  (King James Version)
As vinegar to the teeth, and as smoke to the eyes, so is the sluggard to them that send him.

Proverbs 25:13 Proverbs 25:20

as smoke
As the acidity of vinegar causes the unpleasantness and pain to the teeth, and by softening and dissolving the alkali of the bone, impairs their texture, and renders them incapable of mastication; and as smoke, by irritating the tender vessels, causes the eyes to smart, and prevents distinct vision; so a sluggish messenger is a continual vexation and loss to those by whom he is employed.
Isaiah 65:5

Matthew 25:26 ; Romans 12:11 ; Hebrews 6:12
