1 Samuel 17:4-15

A giant nearly ten feet tall stepped out from the Philistine line into the open, Goliath from Gath. He had a bronze helmet on his head and was dressed in armor—126 pounds of it! He wore bronze shin guards and carried a bronze sword. His spear was like a fence rail—the spear tip alone weighed over fifteen pounds. His shield bearer walked ahead of him. Goliath stood there and called out to the Israelite troops, “Why bother using your whole army? Am I not Philistine enough for you? And you’re all committed to Saul, aren’t you? So pick your best fighter and pit him against me. If he gets the upper hand and kills me, the Philistines will all become your slaves. But if I get the upper hand and kill him, you’ll all become our slaves and serve us. I challenge the troops of Israel this day. Give me a man. Let us fight it out together!” When Saul and his troops heard the Philistine’s challenge, they were terrified and lost all hope. Enter 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.
