1 Samuel 17:40-44

And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd’s bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine.

And the Philistine came on and drew near unto David; and the man that bare the shield went before him.

And when the Philistine looked about, and saw David, he disdained him: for he was but a youth, and ruddy, and of a fair countenance.

And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.

And the Philistine said to David, Come to me, and I will give thy flesh unto the fowls of the air, and to the beasts of the field.
