1 Samuel 17:12-15
12-15Enter David. He was the son of Jesse the Ephrathite from Bethlehem in Judah. Jesse, the father of eight sons, was himself too old to join Saul's army. Jesse's three oldest sons had followed Saul to war. The names of the three sons who had joined up with Saul were Eliab, the firstborn; next, Abinadab; and third, Shammah. David was the youngest son. While his three oldest brothers went to war with Saul, David went back and forth from attending to Saul to tending his father's sheep in Bethlehem.
16Each morning and evening for forty days, Goliath took his stand and made his speech.
