1 Samuel 17:8-17
English Standard Version
Chapter 17
8He stood and shouted to the ranks of Israel, "Why have you come out to draw up for battle? Am I not a Philistine, and are you not servants of Saul? Choose a man for yourselves, and let him come down to me. 9If 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." 10And the Philistine said, "I defy the ranks of Israel this day. Give me a man, that we may fight together." 11When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid.
12Now David was the son of an Ephrathite of Bethlehem in Judah, named Jesse, who had eight sons. In the days of Saul the man was already old and advanced in years.
13The three oldest sons of Jesse had followed Saul to the battle. And the names of his three sons who went to the battle were Eliab the firstborn, and next to him Abinadab, and the third Shammah.
14David was the youngest. The three eldest followed Saul,
15but David went back and forth from Saul to feed his father 's sheep at Bethlehem.
16For forty days the Philistine came forward and took his stand, morning and evening.
