Absalom had made Amasa commander of the army in place of Joab. Amasa was the son of Jether. Jether belonged to the family line of Ishmael. He had married Abigail. She was the daughter of Nahash and the sister of Zeruiah. Zeruiah was the mother of Joab.
Say to Amasa, ‘Aren’t you my own flesh and blood? You will be the commander of my army for life in place of Joab. If that isn’t true, may God punish me greatly.’ ”
So the hearts of all the men of Judah were turned toward David. All of them had the same purpose in mind. They sent a message to the king. They said, “We want you to come back. We want all your men to come back too.”
