1Sam 17:5-7

5He had a helmet of bronze on his head, and he was armed with a coat of mail; the weight of the coat was five thousand shekels of bronze.6He had greaves of bronze on his legs and a javelin of bronze slung between his shoulders.7The shaft 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.
