I Samuel 17:1-19

Now the Philistines gathered their armies together to battle, and were gathered at Sochoh, which belongs to Judah; they encamped between Sochoh and Azekah, in Ephes Dammim. And Saul and the men of Israel were gathered together, and they encamped in the Valley of Elah, and drew up in battle array against the Philistines. The Philistines stood on a mountain on one side, and Israel stood on a mountain on the other side, with a valley between them. And a champion went out from the camp of the Philistines, named Goliath, from Gath, whose height was six cubits and a span. He had a bronze helmet on his head, and he was armed with a coat of mail, and the weight of the coat was five thousand shekels of bronze. And he had bronze armor on his legs and a bronze javelin between his shoulders. Now the staff of his spear was like a weaver’s beam, and his iron spearhead weighed six hundred shekels; and a shield-bearer went before him. Then he stood and cried out to the armies of Israel, and said to them, “Why have you come out to line up for battle? Am I not a Philistine, and you the servants of Saul? Choose a man for yourselves, and let him come down to me. If he is able to fight with me and kill me, then we will be your servants. But if I prevail against him and kill him, then you shall be our servants and serve us.” And the Philistine said, “I defy the armies of Israel this day; give me a man, that we may fight together.” When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid. Now David was the son of that Ephrathite of Bethlehem Judah, whose name was Jesse, and who had eight sons. And the man was old, advanced in years, in the days of Saul. The three oldest sons of Jesse had gone to follow Saul to the battle. The names of his three sons who went to the battle were Eliab the firstborn, next to him Abinadab, and the third Shammah. David was the youngest. And the three oldest followed Saul. But David occasionally went and returned from Saul to feed his father’s sheep at Bethlehem. And the Philistine drew near and presented himself forty days, morning and evening. Then Jesse said to his son David, “Take now for your brothers an ephah of this dried grain and these ten loaves, and run to your brothers at the camp. And carry these ten cheeses to the captain of their thousand, and see how your brothers fare, and bring back news of them.” Now Saul and they and all the men of Israel were in the Valley of Elah, fighting with the Philistines.
