32 and Jehovah hath turned back his blood on his own head, who hath fallen on two men more righteous and better than he, and slayeth them with the sword,—and my father David knew not—Abner son of Ner, head of the host of Israel, and Amasa son of Jether, head of the host of Judah;
Matthew Henry's Commentary on 1 Kings 2:32
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.
