2 Samuel 3:14

David sent messengers to Ish-bosheth We are not informed what answer Abner gave to David when he required the forementioned condition of him. But it is probable he let him know, as the truth was, that it was not in his power to bring Michal to him without Ish-bosheth's consent, whose sister, as well as subject, she was; at least that it was not safe to attempt it, and therefore advised him to send to her brother, who could not easily deny what he desired. Be this as it may, David sent to Ish- bosheth, and thereby opened to him a door of hope for reconciliation, lest, being desperate, he should use every possible means to hinder Abner from his present design. Saying, Deliver me my wife Who, though she was taken from me by force, and constrained to marry another, yet is my rightful wife. David demands her, both for the affection he still retained for her, and upon a political consideration, that she might strengthen his title to the kingdom.
