1 Samuel 17:14

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.

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.

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

And the Philistine drew near morning and evening, and presented himself forty days.
