1 Kings 2:32

32 The LORD will return his blood on his own head, because he fell on two men more righteous and better than he, and killed them with the sword, and my father David didn't know it, [to wit], Aviner the son of Ner, captain of the host of Yisra'el, and `Amasa the son of Yeter, captain of the host of Yehudah.
