2 Samuel 2:8, 12, 29

Now Abner the son of Ner, captain of Saul’s host, had taken Ish-bosheth the son of Saul, and brought him over to Mahanaim

And Abner the son of Ner, and the servants of Ish-bosheth the son of Saul, went out from Mahanaim to Gibeon.

And Abner and his men went all that night through the Arabah; and they passed over the Jordan, and went through all Bithron, and came to Mahanaim.
