1 Samuel 17:4-7

⁴ And there went out a champion out of the camp of the Philistines, named Goliath, of Gath, whose height was six cubits and a span. ⁵ And he had a helmet of brass upon his head, and he was clad with a coat of mail; and the weight of the coat was five thousand shekels of brass. ⁶ And he had greaves of brass upon his legs, and a javelin of brass between his shoulders. ⁷ And the staff of his spear was like a weaver's beam; and his spear's head [weighed] six hundred shekels of iron: and his shield-bearer went before him.
