Bible Verses About Murder: Joab

The king said to him, “Do as he has said, and fall on him, and bury him; that you may take away the blood, which Joab shed without cause, from me and from my father’s house.

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: Abner the son of Ner, captain of the army of Israel, and Amasa the son of Jether, captain of the army of Judah.
