1 Kings 2:29-34

29 King Solomon was told that Joab had fled to the tent of the Lord and was beside the altar. Then Solomon ordered Benaiah son of Jehoiada, “Go, strike him down!”

30 So Benaiah entered the tent of the Lord and said to Joab, “The king says, ‘Come out!’”
But he answered, “No, I will die here.”
Benaiah reported to the king, “This is how Joab answered me.”

31 Then the king commanded Benaiah, “Do as he says. Strike him down and bury him, and so clear me and my father’s house of the guilt of the innocent blood that Joab shed.

32 The Lord will repay him for the blood he shed, because without the knowledge of my father David he attacked two men and killed them with the sword. Both of them—Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army—were better men and more upright than he.

33 May the guilt of their blood rest on the head of Joab and his descendants forever. But on David and his descendants, his house and his throne, may there be the Lord’s peace forever.”

34 So Benaiah son of Jehoiada went up and struck down Joab and killed him, and he was buried on his own land in the desert.
