That is, about 9 feet 9 inches or about 3 meters 5He had a bronze helmet on his head and wore a coat of scale armor of bronze weighing five thousand shekels That is, about 125 pounds or about 58 kilograms ; 6on his legs he wore bronze greaves, and a bronze javelin was slung on his back.

7His spear shaft was like a weaver’s rod, and its iron point weighed six hundred shekels. That is, about 15 pounds or about 6.9 kilograms His shield bearer went ahead of him. 8Goliath stood and shouted to the ranks of Israel, “Why do you come out and line up for battle? Am I not a Philistine, and are you not the servants of Saul? Choose a man and have him come down to me. 9If he is able to fight and kill me, we will become your subjects; but if I overcome him and kill him, you will become our subjects and serve us.”
