Abner son of Ner, commander of Saul’s army, took Saul’s son Ish-bosheth and moved him to Mahanaim.

Abner son of Ner and soldiers of Ish-bosheth son of Saul marched out from Mahanaim to Gibeon.

So Abner and his men marched through the Arabah all that night. They crossed the Jordan, marched all morning, and arrived at Mahanaim.

David had arrived at Mahanaim by the time Absalom crossed the Jordan with all the men of Israel.

When David came to Mahanaim, Shobi son of Nahash from Rabbah of the Ammonites, Machir son of Ammiel from Lo-debar, and Barzillai the Gileadite from Rogelim

Barzillai was a very old man—80 years old—and since he was a very wealthy man, he had provided for the needs of the king while he stayed in Mahanaim.
