28 When the news came to Jo'ab--for Jo'ab had supported Adoni'jah although he had not supported Ab'salom--Jo'ab fled to the tent of the Lord and caught hold of the horns of the altar. 29 And when it was told King Solomon, "Jo'ab has fled to the tent of the Lord, and behold, he is beside the altar," Solomon sent Benai'ah the son of Jehoi'ada, saying, "Go, strike him down." 30 So Benai'ah came to the tent of the Lord, and said to him, "The king commands, 'Come forth.'" But he said, "No, I will die here." Then Benai'ah brought the king word again, saying, "Thus said Jo'ab, and thus he answered me." 31 The king replied to him, "Do as he has said, strike him down and bury him; and thus take away from me and from my father's house the guilt for the blood which Jo'ab shed without cause. 32 The Lord will bring back his bloody deeds upon his own head, because, without the knowledge of my father David, he attacked and slew with the sword two men more righteous and better than himself, Abner the son of Ner, commander of the army of Israel, and Ama'sa the son of Jether, commander of the army of Judah. 33 So shall their blood come back upon the head of Jo'ab and upon the head of his descendants for ever; but to David, and to his descendants, and to his house, and to his throne, there shall be peace from the Lord for evermore." 34 Then Benai'ah the son of Jehoi'ada went up, and struck him down and killed him; and he was buried in his own house in the wilderness.

(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.
