Thou knowest also what Joab the son of Sarvia hath done to me, what he did to the two captains of the army of Israel, to Abner the son of Ner, and to Amasa the son of Jether: whom he slew, and shed the blood of war in peace, and put the blood of war on his girdle that was about his loins, and in his shoes that were on his feet.
Ishodad of Merv
[David] orders Solomon to punish [Joab], not out of viciousness or hatred for him but because he knew that he was wicked and that, if he had acted with hostility against him who was a mature man, he would act even worse against a young man, so that the kingdom would become unstable, and the house would not be firmly established. Therefore he entrusts his son with the revenge against him who had offended him, in order that, after the killing of that evil man by the hand of the new king, he might be feared by everyone, and no revolt might ever occur.
