1 Samuel 17:5-7

5And he had a helmet of bronze upon his head, and he was clothed with a corselet of scales; and the weight of the corselet was five thousand shekels of bronze.

6And he had greaves of bronze upon his legs, and a javelin of bronze between his shoulders.

7And the shaft of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron; and the shield-bearer went before him.
