Proverbs 26:21-25

Like charcoal to hot embers and wood to fire, So is a contentious person to kindle strife.

The words of a gossiper are like dainty morsels, And they go down into the innermost parts of the body.

Like an earthenware vessel overlaid with silver impurities Are burning lips and a wicked heart.

One who hates disguises it with his lips, But he harbors deceit in his heart.

When he speaks graciously, do not believe him, Because there are seven abominations in his heart.
