1 Kings 2:32

And the Lord has returned upon his own head the blood of his unrighteousness, inasmuch as he attacked two men more righteous and better than himself, and slew them with the sword, and my father David knew not of their blood, [even] Abenner the son of Ner the commander-in-chief of Israel, and Amessa the son of Jether the commander-in-chief of Juda.
