1st Samuel 17:8

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.

10 And the Philistine said, I defy the armies of Israel this day; give me a man, that we may fight together.

11 And when Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid.
