II Samuel 2:8, 12, 29

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

Now Abner the son of Ner, and the servants of Ishbosheth the son of Saul, went out from Mahanaim to Gibeon.

Then Abner and his men went on all that night through the plain, crossed over the Jordan, and went through all Bithron; and they came to Mahanaim.
