Proverbs 6:32

32. Whose committeth adultery, taking all the circumstances and consequences into the account, acts like a madman or simpleton like one who seeks to destroy his own life. Unlike the thief who steals to satisfy his hunger, he unnecessarily robs a man of his wife, and when discovered will not merely lose his property, but forfeit his life. See Leviticus 20:10; Deuteronomy 22:22. The argument here is a fortiori, from the less to the greater. If a thief is punished for stealing to satisfy his hunger, how much more the adulterer!
