1 Samuel 17:40-47

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

41So the Philistine came, and began drawing near to David, and the man who bore the shield went before him.

42And when the Philistine looked about and saw David, he disdained him; for he was only a youth, ruddy and good-looking.

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.

44And the Philistine said to David, “Come to me, and I will give your flesh to the birds of the air and the beasts of the field!”

45Then David said to the Philistine, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied.

46This day the Lord will deliver you into my hand, and I will strike you and take your head from you. And this day I will give the carcasses of the camp of the Philistines to the birds of the air and the wild beasts of the earth, that all the earth may know that there is a God in Israel.

47Then all this assembly shall know that the Lord does not save with sword and spear; for the battle is the Lord’s, and He will give you into our hands.”
