2 Samuel 2:8, 12, 29

Meanwhile, Abner son of Ner, the commander of Saul’s army, had taken Ish-Bosheth son of Saul and brought him over to Mahanaim.

Abner son of Ner, together with the men of Ish-Bosheth son of Saul, left Mahanaim and went to Gibeon.

All that night Abner and his men marched through the Arabah. They crossed the Jordan, continued through the morning hours and came to Mahanaim.
