Proverbs 6:34
King James Version
“For jealousy the rage of a man: therefore he will not spare in the day of vengeance.”
Context
31But he be found, he shall restore sevenfold; he shall give all the substance of his house.
32whoso committeth adultery with a woman lacketh understanding: he doeth it destroyeth his own soul.
33A wound and dishonour shall he get; and his reproach shall not be wiped away.
34For jealousy the rage of a man: therefore he will not spare in the day of vengeance.
35He will not regard any ransom; neither will he rest content, though thou givest many gifts.
