Proverbs 26:21-23

²¹As dead coals at quick coals, and trees at the fire, or As dead coals to quick coals, and wood to fire; so a wrathful man (that) raiseth chidings. (Like dead coals to burning coals, and wood to fire, is an angry person who raiseth up arguments, or strife.)

²²The words of a privy backbiter be as simple (or The words of a gossip be tasty); and those come till to the innerest things of the heart.

²³As if thou wouldest adorn a vessel of earth, (that is, a cheap pot made out of clay), with the dross of silver, so be swelling lips fellowshipped with a full wicked heart.
