2 Samuel 17:25

Now Abessalom had set Amessai over the army in the room of Joab. Amessai was the son of a man whose name was Jether. He was a Jezraelite, and had married Abigaia, a daughter of Naas, and a sister of Saruia, the mother of Joab.

And Abessalom appointed Amessai in the room of Joab over the host. And Amessai was the son of a man whose name was Jether of Jezrael: he went in to Abigaia the daughter of Naas, the sister of Saruia the mother of Joab.
