Proverbs 26:18-25

As a mad man who casteth firebrands, Arrows, and death, So is the man that deceiveth his neighbour, And saith, Am not I in sport? Where no wood is, there the fire goeth out: So where there is no talebearer, the strife ceaseth. 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.
