Then King Solomon made a vow before the LORD : “May God strike me and even kill me if Adonijah has not sealed his fate with this request.
The LORD has confirmed me and placed me on the throne of my father, David; he has established my dynasty as he promised. So as surely as the LORD lives, Adonijah will die this very day!”
So King Solomon ordered Benaiah son of Jehoiada to execute him, and Adonijah was put to death.
Then the king said to Abiathar the priest, “Go back to your home in Anathoth. You deserve to die, but I will not kill you now, because you carried the Ark of the Sovereign LORD for David my father and you shared all his hardships.”
So Solomon deposed Abiathar from his position as priest of the LORD, thereby fulfilling the prophecy the LORD had given at Shiloh concerning the descendants of Eli.
Joab had not joined Absalom’s earlier rebellion, but he had joined Adonijah’s rebellion. So when Joab heard about Adonijah’s death, he ran to the sacred tent of the LORD and grabbed on to the horns of the altar.
When this was reported to King Solomon, he sent Benaiah son of Jehoiada to execute him.
Benaiah went to the sacred tent of the LORD and said to Joab, “The king orders you to come out!” But Joab answered, “No, I will die here.” So Benaiah returned to the king and told him what Joab had said.
“Do as he said,” the king replied. “Kill him there beside the altar and bury him. This will remove the guilt of Joab’s senseless murders from me and from my father’s family.
The LORD will repay him for the murders of two men who were more righteous and better than he. For my father knew nothing about the deaths of Abner son of Ner, commander of the army of Israel, and of Amasa son of Jether, commander of the army of Judah.
May their blood be on Joab and his descendants forever, and may the LORD grant peace forever to David, his descendants, his dynasty, and his throne.”
