"You yourself know what Joab, the son of Zeruiah, did to me. You know that he killed Abner, the son of Ner, and Amasa, the son of Jether. They were the two commanders of Israel's armies. He killed them in a time of peace. It wasn't a time of war. Joab spilled the blood of Abner and Amasa. It stained the belt that was around his waist. It also stained the sandals on his feet.
