1 Samuel 17:4-10

Then a champion came out from the camp of the Philistines named Goliath of Gath, whose height was six cubits and a span. He had a bronze helmet on his head, and wore a coat of scale-armor (overlapping metal plates) which weighed 5,000 shekels of bronze. He had bronze shin protectors on his legs and a bronze javelin hung between his shoulders. The [wooden] shaft of his spear was like a weaver’s beam; the blade-head of his spear weighed six hundred shekels of iron. And a shield-bearer walked in front of him. Goliath stood and shouted to the battle lines of Israel, saying to them, “Why have you come out to draw up for battle? Am I not the Philistine and are you not servants of Saul? Choose a man for yourselves and have him come down to me. If he is able to fight with me and kill me, then we will become your servants; but if I prevail against him and kill him, then you shall become our servants and serve us.” Again the Philistine said, “I defy the battle lines of Israel this day; give me a man so that we may fight together.”
