28 And the report came to Joab (for Joab had turned after Adonijah, though he had not turned after Absalom); and Joab fled to the tent of Jehovah, and caught hold of the horns of the altar. 29 And it was told king Solomon that Joab had fled to the tent of Jehovah; and behold, he is by the altar. And Solomon sent Benaiah the son of Jehoiada, saying, Go, fall on him. 30 And Benaiah came to the tent of Jehovah and said to him, Thus saith the king: Come forth. And he said, No; for I will die here. And Benaiah brought the king word again, saying, Thus said Joab, and thus he answered me. 31 And the king said to him, Do as he has said, and fall upon him, and bury him; and take away the innocent blood, which Joab shed, from me and from the house of my father. 32 And Jehovah shall requite the blood which he shed upon his own head, because he fell upon two men more righteous and better than he, and slew them with the sword, without my father David's knowledge: Abner the son of Ner, captain of the host of Israel, and Amasa the son of Jether, captain of the host of Judah. 33 And their blood shall be requited upon the head of Joab, and upon the head of his seed for ever; but upon David, and upon his seed, and upon his house, and upon his throne, shall there be peace for ever from Jehovah. 34 And Benaiah the son of Jehoiada went up and fell upon him, and put him to death; and he was buried in his own house in the wilderness.

Commentary on 1 Kings 2:26-34
(Read 1 Kings 2:26-34)
Solomon's words to Abiathar, and his silence, imply that some recent conspiracies had been entered into. Those that show kindness to God's people shall have it remembered to their advantage. For this reason Solomon spares Abiathar's life, but dismisses him from his offices. In case of such sins as the blood of beasts would atone for, the altar was a refuge, but not in Joab's case. Solomon looks upward to God as the Author of peace, and forward to eternity as the perfection of it. The Lord of peace himself gives us that peace which is everlasting.
