Absalom had made Amasa captain of the army instead of Joab. Amasa was the son of a man named Jether the Ishmaelite. Amasa’s mother was Abigail daughter of Nahash and sister of Zeruiah, Joab’s mother.
Shobi, Makir, and Barzillai were at Mahanaim when David arrived. Shobi son of Nahash was from the Ammonite town of Rabbah. Makir son of Ammiel was from Lo Debar, and Barzillai was from Rogelim in Gilead.
Then land was given to the tribe of Manasseh, Joseph’s first son. Manasseh’s first son was Makir, the father of Gilead. Makir was a great soldier, so the lands of Gilead and Bashan were given to his family.
