Goliath
1 Samuel 17:4-11
4
And there went out a champion out of the camp of the Philistines, named Goliath, of Gath, whose height was six cubits and a span.
5
And he had an helmet of brass upon his head, and he was armed 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 target 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 one bearing a shield 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 to 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
When Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid.
