1 Samuel 17:5-7

He had a helmet of bronze on his head, and he was armed with a coat of mail, and the weight of the coat was five thousand shekels of bronze. And he had bronze armor on his legs, and a javelin of bronze slung between his shoulders. The 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.
