1 Samuel 17:13 WEB

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

¹²  Now David was the son of that Ephrathite of Bethlehem Judah, whose name was Jesse; and he had eight sons: and the man was an old man in the days of Saul, stricken [in years] among men.

¹³  The three eldest sons of Jesse had gone after 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.

¹⁴  David was the youngest; and the three eldest followed Saul.

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