Proverbs 26:21-25

²¹A hearth for coals, and wood for fire; and railing man for the tumult of strife.

²²The words of cunning knaves are soft; but they strike even to the inmost parts of the bowels.

²³Silver dishonestly given is to be considered as a potsherd: smooth lips cover a grievous heart.

²⁴A weeping enemy promises all things with his lips, but in his heart he contrives deceit.

²⁵Though your enemy entreat you with a loud voice, consent not: for there are seven abominations in his heart.
