Midrash su II Samuele 18:15

(Ib. b) Our Rabbis were taught: Manasseh used to interpret the book of Leviticus in fifty-five ways, corresponding to the number of years which he reigned. Achab, eighty-five, and Jeroboam, one hundred and three. We are taught in a Baraitha that R. Mair used to say: "Absalom has no share in the world to come, as it is said (II Sam. 18, 15) Smote Absalom and slew him, i.e., smote Absalom — in this world, and slew him, in the world to come." R. Simon b. Elazar said in the name of R. Mair: "Achaz, Achazyah and all the kings of Israel concerning whom it is written, And he did evil in the eyes of the Lord,' will not enjoy resurrection, but are also not sentenced to Gehena." (II Kings 21, 16) Moreover, Manasseh shed innocent blood very much till he had filled therewith Jerusalem from one end to another; beside his sin wherewith he induced Judah to sin, in doing that which was evil in the sight of the Lord. Here (in Babylon) it was explained that the passage he had filled Jerusalem from one end to another, refers to the slaughtering of Isaiah. In the West (Palestine) it was explained that it refers to an image which he made of a thousand persons in weight. And those who were engaged in carrying it from one place to another would die [because of the great exertions]. Whose principles does Rabba b. b. Chana follow when he said: "A soul of a single righteous man is equal to the whole world?" It is in accordance With him who says that Manasseh has killed Isaiah. [Since the passage calls it he had killed Jerusalem.]

Rabbi Eliezer said: Come and see the integrity and perfection of that man, for he said to Joab, Even if thou wouldst give me gold and silver I would not transgress the king's commands which he commanded thee, as it is said, "And the man said unto Joab, Though I should receive a thousand (pieces of) silver in mine hand" (2 Sam. 18:12). Joab said to him: I beseech thee, show me the place where Absalom is hanging. But he did not consent. Joab began to bend the knee, and to prostrate himself before him, as it is said, "Then said Joab, Shall I not entreat thee in this wise?" (2 Sam. 18:14). Then he took (Joab) by his arm, and showed him the place where Absalom was hanging. Everyone who transgresses the commandment "Honour thy father" is accounted as though he had transgressed the Decalogue. Therefore was (Absalom) pierced by ten spears, as it is said, "And ten young men that bare Joab's armour compassed about and smote Absalom; and slew him" (2 Sam. 18:15).
