1 Samuel 17:40-47

⁴⁰Then he took his staff in his hand and chose for himself five smooth stones from the brook, and put them in the shepherd’s bag which he had, that is, in his shepherd’s pouch, and his sling was in his hand; and he approached the Philistine.

⁴¹Then the Philistine came and approached David, with the shield-bearer in front of him. ⁴²When the Philistine looked and saw David, he was contemptuous of him; for he was only a youth, and reddish, with a handsome appearance. ⁴³So the Philistine said to David, “Am I a dog, that you come to me with sticks?” And the Philistine cursed David by his gods. ⁴⁴The Philistine also said to David, “Come to me, and I will give your flesh to the birds of the sky and the wild animals.” ⁴⁵But David said to the Philistine, “You come to me with a sword, a spear, and a saber, but I come to you in the name of the Lord of armies, the God of the armies of Israel, whom you have defied. ⁴⁶This day the Lord will hand you over to me, and I will strike you and remove your head from you. Then I will give the dead bodies of the army of the Philistines this day to the birds of the sky and the wild animals of the earth, so that all the earth may know that there is a God in Israel, ⁴⁷and that this entire assembly may know that the Lord does not save by sword or by spear; for the battle is the Lord’s, and He will hand you over to us!”
