David was not long permitted to enjoy the ease of life at court. The aggressive manner assumed by Goliath drove him to the front. It was a curious chance that designated David to be the slayer of Goliath, who was allied with him by the ties of blood. Goliath, it will be remembered, was the son of the Moabitess Orpah, (27) the sister-in-law of David's ancestress Ruth, and her sister as well, both having been the daughters of the Moabite king Eglon. (28) David and Goliath differed as widely as their grandams, for in contrast to Ruth, the pious, religious Jewess, Orpah had led a life of unspeakable infamy. Her son Goliath was jeered at as "the son of a hundred fathers and one mother." (29) But God lets naught go unrewarded, even in the wicked. In return for the forty steps Orpah had accompanied her mother-in-law Naomi, (30) Goliath the Philistine, her son, was permitted to display his strength and skill for forty days, and in return for the four tears Orpah had shed on parting from her mother-in-law, she was privileged to give birth to four giant sons. (31)
Of the four, Goliath was the strongest and greatest. What the Scriptures tell about him is but a small fraction of what might have been told. The Scriptures refrain intentionally from expatiating upon the prowess of the miscreant. Nor do they tell how Goliath, impious as he was, dared challenge the God of Israel to combat with him, and how he tried by every means in his power to hinder the Israelites in their Divine worship. Morning and evening he would appear in the camp at the very time when the Israelites were preparing to say the Shema. (32)
All the more cause, then, for David to hate Goliath and determine to annihilate him. His father encouraged him to oppose Goliath, for he considered it David's duty to protect Saul the Benjamite against the giant, as Judah, his ancestor, had in ancient days pledged himself for the safety of Benjamin, the ancestor of Saul.
Scarcely did David begin to move toward Goliath, when the giant became conscious of the magic power of the youth. The evil eye David cast on his opponent sufficed to afflict him with leprosy,
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.
