1 Samuel 17:5-9

And he had a bronze helmet on his head, and he wore scale-armor which weighed five thousand shekels of bronze.

He also had bronze greaves on his legs and a bronze saber slung between his shoulders.

The shaft of his spear was like a weaver’s beam, and the head of his spear weighed six hundred shekels of iron; and his shield-carrier walked in front of him.

He stood and shouted to the ranks of Israel and said to them, “Why do you come out to draw up in battle formation? Am I not the Philistine, and you the servants of Saul? Choose a man as your representative and have him come down to me.

If he is able to fight me and kill me, then we will become your servants; but if I prevail against him and kill him, then you shall become our servants and serve us.”
