1 Samuel 17:4-10

Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span. He had a bronze helmet on his head, and he was clothed with scale-armor which weighed five thousand shekels of bronze. He also had bronze greaves on his legs and a bronze javelin slung between his shoulders. The shaft of his spear was like a weaver’s beam, and the head of his spear weighed six hundred shekels of iron; his shield-carrier also walked before him. He stood and shouted to the ranks of Israel and said to them, “Why do you come out to draw up in battle array? Am I not the Philistine and you servants of Saul? Choose a man for yourselves and let 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 ranks of Israel this day; give me a man that we may fight together.”
