1 Samuel 17:40-50

40Then he took his [shepherd’s] staff in his hand and chose for himself five smooth stones out of the stream bed, and put them in his shepherd’s bag which he had, that is, in his shepherd’s pouch. With his sling in his hand, he approached the Philistine.

41The Philistine came and approached David, with his shield-bearer in front of him.

42When the Philistine looked around and saw David, he derided and disparaged him because he was [just] a young man, with a ruddy complexion, and a handsome appearance.

43The Philistine said to David, “Am I a dog, that you come to me with [shepherd’s] staffs?” 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 beasts of the field.”

45Then David said to the Philistine, “You come to me with a sword, a spear, and 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 taunted.

46This day the Lord will hand you over to me, and I will strike you down and cut off your head. And I will give the corpses of the army of the Philistines this day to the birds of the sky and the wild beasts 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 with the sword or with the spear; for the battle is the Lord’s and He will hand you over to us.”

48When the Philistine rose and came forward to meet David, David ran quickly toward the battle line to meet the Philistine.

49David put his hand into his bag and took out a stone and slung it, and it struck the Philistine on his forehead. The stone penetrated his forehead, and he fell face down on the ground.

50So David triumphed over the Philistine with a sling and a stone, and he struck down the Philistine and killed him; but there was no sword in David’s hand.
