1st Kings 2:26

23 Then King Solomon took an oath by the Lord, saying, May God's punishment be on me if Adonijah does not give payment for these words with his life.

24 Now by the living Lord, who has given me my place on the seat of David my father, and made me one of a line of kings, as he gave me his word, truly Adonijah will be put to death this day.

25 And King Solomon sent Benaiah, the son of Jehoiada, and he made an attack on him and put him to death.

26 And to Abiathar the priest the king said, Go to Anathoth, to your fields; for death would be your right reward; but I will not put you to death now, because you took up the ark of the Lord God before David my father, and you were with him in all his troubles.

27 So Solomon let Abiathar be priest no longer, so that he might make the word of the Lord come true which he said about the sons of Eli in Shiloh.

28 And news of this came to Joab; for Joab had been one of Adonijah's supporters, though he had not been on Absalom's side. Then Joab went in flight to the Tent of the Lord, and put his hands on the horns of the altar.

29 And they said to King Solomon, Joab has gone in flight to the Tent of the Lord and is by the altar. Then Solomon sent Benaiah, the son of Jehoiada, saying, Go, make an attack on him.
