1 Samuel 17:12

¹⁰  And the Philistine said, I defy the armies of Israel this day; give me a man, that we may fight together.

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 Bethlehemjudah, whose name was Jesse; and he had eight sons: and the man went among men for an old man in the days of Saul.

¹³  And the three eldest sons of Jesse went and followed Saul to the battle: and the names of his three sons that went to the battle were Eliab the firstborn, and next unto him Abinadab, and the third Shammah.

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