2 Samuel 17:24-29

About the time David arrived at Mahanaim, Absalom crossed the Jordan, and the whole army of Israel with him. Absalom had made Amasa head of the army, replacing Joab. (Amasa was the son of a man named Ithra, an Ishmaelite who had married Abigail, daughter of Nahash and sister of Zeruiah, the mother of Joab.) Israel and Absalom set camp in Gilead. When David arrived at Mahanaim, Shobi son of Nahash from Ammonite Rabbah, and Makir son of Ammiel from Lo Debar, and Barzillai the Gileadite from Rogelim brought beds and blankets, bowls and jugs filled with wheat, barley, flour, roasted grain, beans and lentils, honey, and curds and cheese from the flocks and herds. They presented all this to David and his army to eat, “because,” they said, “the army must be starved and exhausted and thirsty out in this wilderness.”
