1 Samuel 17:3-5

King James Version

³ And 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.

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

⁵ And 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.
