1 Samuel 17:12-17

12David was a son of a man named Jesse from the region of Ephrath and the city of Bethlehem in Judah. Jesse had eight sons, and in Saul’s day he was an old man.

13Jesse’s three oldest sons joined Saul’s army for the battle. The firstborn was Eliab, the second was Abinadab, the third was Shammah,

14and David was the youngest. The three oldest joined Saul’s army.

15David went back and forth from Saul’s camp to Bethlehem, where he tended his father’s flock.

16Each morning and evening for 40 days, the Philistine came forward and made his challenge.

17Jesse told his son David, “Take this half-bushel of roasted grain and these ten loaves of bread to your brothers. Take them to your brothers in the camp right away.
