2 Samuel 2:8, 12, 29

But Abner the son of Ner, captain of Saul's host, took 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 walked all that night through the plain, and passed over Jordan, and went through all Bithron, and they came to Mahanaim.
