1 Samuel 17:11-16 Amplified Bible (AMP)

11. When Saul and all Israel heard those words of the Philistine, they were dismayed and greatly afraid.

12. David was the son of an Ephrathite of Bethlehem in Judah named Jesse, who had eight sons. [Jesse] in the days of Saul was old, advanced in years.

13. [His] three eldest sons had followed Saul into battle. Their names were Eliab the firstborn; next, Abinadab; and third, Shammah.

14. David was the youngest. The three eldest followed Saul,

15. But David went back and forth from Saul to feed his father's sheep at Bethlehem.

16. The Philistine came out morning and evening, presenting himself for forty days.
