1 Samuel 17:4-7

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.
