1 Kings 2:32-34

32And the LORD shall return his blood upon his own head, who fell upon two men more righteous and better than he, and slew them with the sword, my father David not knowing of it, that is, Abner the son of Ner, captain of the host of Israel, and Amasa the son of Jether, captain of the host of Judah. 33Their blood shall therefore return upon the head of Joab, and upon the head of his seed for ever: but upon David, and upon his seed, and upon his house, and upon his throne, shall there be peace for ever from the LORD. 34So Benaiah the son of Jehoiada went, and fell upon him, and slew him: and he was buried in his own house in the wilderness.
