Proverbs 6:25-29, 32-33

Do not lust in your heart after her beauty or let her captivate you with her eyes. For a prostitute can be had for a loaf of bread, but another man’s wife preys on your very life. Can a man scoop fire into his lap without his clothes being burned? Can a man walk on hot coals without his feet being scorched? So is he who sleeps with another man’s wife; no one who touches her will go unpunished.

But a man who commits adultery has no sense; whoever does so destroys himself. Blows and disgrace are his lot, and his shame will never be wiped away.
