1 Kings 2:30-34

So Benaiah came to the tent of the Lord and said to him, “This is what the king has said: ‘Come out.’ ” But he said, “No, for I will die here.” So Benaiah brought back word to the king, saying, “This is what Joab spoke, and so he answered me.”

And the king said to him, “Do just as he has spoken, and execute him and bury him, so that you may remove from me and from my father’s house the blood which Joab shed without justification.

The Lord will return his blood on his own head, because he struck two men more righteous and better than he, and killed them with the sword, while my father David did not know about it: Abner the son of Ner, commander of the army of Israel, and Amasa the son of Jether, commander of the army of Judah.

So their blood shall return on the head of Joab and on the head of his descendants forever; but for David and his descendants, and his house and his throne, may there be peace from the Lord forever.”

Then Benaiah the son of Jehoiada went up and struck him and put him to death, and he was buried at his own house in the wilderness.
