And Absalom put Amasa at the head of the army in place of Joab. Now Amasa was the son of a man named Ithra the Ishmaelite, who had been the lover of Abigail, the daughter of Jesse, sister of Zeruiah, Joab's mother.
And David said, What have I to do with you, you sons of Zeruiah, that you put yourselves against me today? is it right for any man in Israel to be put to death today? for I am certain today that I am king in Israel.
And Joab, the son of Zeruiah, and the servants of David, went out and came face to face with them by the pool of Gibeon; and they took up their position, facing one another on opposite sides of the pool.
While I, though I am crowned king, have little strength, and these men, the sons of Zeruiah, are out of my control: may the Lord give to the evil-doer the reward of his evil-doing!
Then David said to Ahimelech the Hittite, and to Abishai, the son of Zeruiah, brother of Joab, Who will go down with me to the tents of Saul? And Abishai said, I will go down with you.
