1 Samuel 17:12-15

ASV(i) 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.
