1 Samuel 17:5-9

⁵ And he had a helmet of brass upon his head, and he was clad with a coat of mail; and the weight of the coat was five thousand shekels of brass. ⁶ And he had greaves of brass upon his legs, and a javelin of brass between his shoulders. ⁷ And the staff 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. ⁸ And he stood and cried unto the armies of Israel, and said unto them, Why are ye come out to set your battle in array? am not I a Philistine, and ye servants to Saul? choose you a man for you, and let him come down to me. ⁹ If he be able to fight with me, and kill me, then will we be your servants; but if I prevail against him, and kill him, then shall ye be our servants, and serve us.
