Proverbs 26:21-25

As coals are to burning coals, and wood to fire; so is a contentious man to kindle strife.

The words of a talebearer are as wounds, and they go down into the innermost parts of the belly.

Burning lips and a wicked heart are like a potsherd covered with silver dross.

He that hateth dissembleth with his lips, and layeth up deceit within him;

When he speaketh fair, believe him not: for there are seven abominations in his heart.
