1 Samuel 17:13 ASV

¹¹  And 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 Beth-lehem-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  And the three eldest sons of Jesse had gone after Saul to the battle: and the names of his three sons that went to the battle were Eliab the first-born, and next unto him Abinadab, and the third Shammah.

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

¹⁵  Now David went to and fro from Saul to feed his father's sheep at Beth-lehem.
