Joab's execution 2:28-35

Perhaps because Solomon had shown Adonijah mercy when he fled to the altar (1:50-52) Joab sought refuge from Solomon for participating in Adonijah's rebellion there too. Joab, however, was a murderer as well as a rebel. Consequently Solomon had him executed in obedience to the Mosaic Law (Exod. 21:14). Manslayers, but not murderers, received sanctuary at the altar. David's house shared the guilt for Joab's murders as long as he remained alive (v. 31). By executing him Solomon cleared the way for God to bless him and his throne. God would punish Joab's house but bless David's house (v. 33). Solomon honored Joab for his service to David by burying him in his own land in Judah (v. 34; cf. 2 Sam. 2:32).
