2 Samuel 2:8, 12, 29

But Abner the son of Ner, commander of Saul’s army, took Ish-bosheth the son of Saul and brought him over to Mahanaim

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. They crossed the Jordan, and marching the whole morning, they came to Mahanaim.
