1 Samuel 17:41

Saul dressed David with his clothing. He put a helmet of bronze on his head, and he clad him with a coat of mail.

David strapped his sword on his clothing and he tried to move, for he had not tested it. David said to Saul, “I can’t go with these, for I have not tested them.” Then David took them off.

He took his staff in his hand, and chose for himself five smooth stones out of the brook, and put them in the pouch of his shepherd’s bag which he had. His sling was in his hand; and he came near to the Philistine.

When the Philistine looked around and saw David, he disdained him; for he was but a youth, and ruddy, and had a good looking face.

The Philistine said to David, “Am I a dog, that you come to me with sticks?” The Philistine cursed David by his gods.

The Philistine said to David, “Come to me, and I will give your flesh to the birds of the sky and to the animals of the field.”
