Goliath was encased, from top to toe, in several suits of armor, and David did not know how to remove them and cut off the head of the giant. At this juncture Uriah the Hittite offered him his services, but under the condition that David secure him an Israelitish wife. David accepted the condition, and Uriah in turn showed him how the various suits of armor were fastened together at the heels of the giant's feet.
David's victory naturally added fuel to the fire of Saul's jealousy. Saul sent Abner, his general, to make inquiry whether David, who, he knew, was of the tribe of Judah, belonged to the clan of the Perez or to the clan of the Zerah. In the former case his suspicion that David was destined for kingship would be confirmed. Doeg, David's enemy from of old, observed that David, being the descendant of the Moabitess Ruth, did not even belong to the Jewish communion, and Saul need entertain no fears from that quarter. A lively discussion arose between Abner and Doeg, as to whether the law in Deuteronomy regarding Moabites affected women as well as men. Doeg, an expert dialectician, brilliantly refuted all of Abner's arguments in favor of the admission of Moabitish women. Samuel's authority had to be appealed to in order to establish for all times the correctness of Abner's view. Indeed, the dispute could be settled only by recourse to threats of violence. Ithra, the father of Amasa, in Arab fashion, for which reason he was sometimes called the Ishmaelite, threatened to hew down any one with his sword who refused to accept Samuel's interpretation of the law, that male Moabites and male Ammonites are forever excluded from the congregation of Israel, but not Moabite and Ammonite women.
