Jonathan, the king's son, and Michal, the king's daughter, also learnt to love the shepherd-singer as he went in and out before the king. Then Saul made him one of his fighting chiefs, who stood daily before him; and whenever his sickness came upon the king he called for the shepherd-harper, and David played music both sad and gay until the cloud passed from the king's mind. Sometimes David stayed at Gibeah, where the king's house was, and sometimes at Bethlehem; and always once a year he went home to the great family feast of the new moon, when all his father's relatives were gathered together. III. The fighting between King Saul and the Philistine tribes, who lived near the seacoast, never ceased; for the Philistines had made up their minds to make the men of Israel their servants, and King Saul was determined that his people should be free. Once upon a time the Philistines gathered their young men, and came, with their battle-flags and drums, up the great Vale of Elah, the valley of oaks, to attack Saul's people. Stopping at the village of Succoth, they chose a secure place, and put up their black tents among the thick bushes, camping about ten miles from the round hill of Bethlehem. [Illustration: David and Goliath.] Then King Saul sent out messengers to sound the war-horns up and down the valleys, and gather his fighting-men to drive back their old enemies. Three of David's brothers grasped their spears and bows, and joined King Saul with the men of the tribe of Judah; but David stayed for the time at Bethlehem, to take care of his old father and the flocks. In those days soldiers had to find their own food, and armies sat down before each other for many days before they began to fight. After a time Jesse sent David with asses laden with corn and cakes for his brothers, and ten little cheeses for their captain; and David led them through the hills and down the wide glen to the camping-place opposite Succoth, where the king's men looked across the valley to their foes on the opposite slope, while the river ran between. Then one day the Philistines sent out a champion, a giant named Goliath of Gath, who wore a helmet of brass and a brazen coat of mail of very great weight. He had greaves of brass upon his legs, and a gorget of brass between his shoulders. The staff of his spear was like a weaver's beam, and his shield-bearer went before him. This champion sent a boastful challenge to the Israelites, bidding them send out a man to fight with him. "If he be able to fight with me, and to kill me, then will we be your servants," ran the message; "but if I prevail against him, and kill him, then shall ye be our servants." This challenge he repeated for forty days, but there was no man found among the men of Israel who dared to go out against Goliath of Gath.
