1 Samuel 17:5 KJV

3And the Philistines stood on a mountain on the one side, and Israel stood on a mountain on the other side: and there was a valley between them.

4And there went out a champion out of the camp of the Philistines, named Goliath, of Gath, whose height was six cubits and a span.

5And he had an helmet of brass upon his head, and he was armed with a coat of mail; and the weight of the coat was five thousand shekels of brass.

6And he had greaves of brass upon his legs, and a target of brass between his shoulders.

7And the staff of his spear was like a weaver’s beam; and his spear’s head weighed six hundred shekels of iron: and one bearing a shield went before him.
