1 Kings 2:30-32

Young's Literal Translation

³⁰ And Benaiah cometh in unto the tent of Jehovah, and saith unto him, `Thus said the king, Come out;' and he saith, `Nay, but here I die.' And Benaiah bringeth back the king word, saying, `Thus spake Joab, yea, thus he answered me.'

³¹ And the king saith to him, `Do as he hath spoken, and fall upon him, and thou hast buried him, and turned aside the causeless blood which Joab shed, from off me, and from off the house of my father;

³² and Jehovah hath turned back his blood on his own head, who hath fallen on two men more righteous and better than he, and slayeth them with the sword, -- and my father David knew not -- Abner son of Ner, head of the host of Israel, and Amasa son of Jether, head of the host of Judah;
