1 Samuel 17:5-9

⁵ He had a helmet of bronze on his head, and he was armed with a coat of mail, and the weight of the coat was five thousand shekels of bronze. ⁶ And he had greaves of bronze upon his legs, and a javelin of bronze slung between his shoulders. ⁷ And the shaft 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 He stood and shouted to the ranks of Israel, "Why have you come out to draw up for battle? Am I not a Philistine, and are you not servants of Saul? Choose a man for yourselves, and let him come down to me. ⁹ If he is able to fight with me and kill me, then we will be your servants; but if I prevail against him and kill him, then you shall be our servants and serve us."
