1 Samuel 17:12-17

12Now David was 1the son of 2the 3Ephrathite of Bethlehem in Judah, the man whose name was Jesse, and 4he had eight sons. And 5Jesse was old in the days of Saul, advanced in years among men. 13The three older sons of Jesse had 6followed Saul to the battle. And 7the names of his three sons who had gone into the battle were Eliab the firstborn, and second to him, Abinadab, and the third, Shammah. 14So 8David was the youngest. Now the three oldest followed Saul, 159but David went back and forth from Saul 10to tend his father’s flock at Bethlehem. 16And the Philistine came forward morning and evening, and took his stand for forty days.
