2 Samuel 2:8

Partly out of envy and malice against David; and partly out of his own ambition and desire of rule, because he knew that Ish-bosheth would have only the name of king, whilst he had the power. Ish-bosheth, called also Esh-baal, 1 Chronicles 8:33, 1 Chronicles 9:39; it being usual with the Hebrews, instead of Baal, the name of false gods, to put Bosheth, which signifies shame, or confusion, or a shameful thing; as appeareth by comparing Judges 9:53, with 2 Samuel 11:21; and 2 Samuel 4:4, with 1 Chronicles 8:31; and from Jeremiah 3:21 Hosea 9:10. Mahanaim; a place beyond Jordan, whither he carried him; partly to secure those brave and valiant men of Jabesh-gilead to himself; and principally because this place was most remote from David, and from the Philistines too; and therefore here he might recruit his forces with less disturbance than in other places.
