1 Samuel 17:45-47

New Revised Standard Version, Anglicised Catholic Edition

⁴⁵ But David said to the Philistine, ‘You come to me with sword and spear and 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. ⁴⁶ This very day the Lord will deliver you into my hand, and I will strike you down and cut off your head; and I will give the dead bodies of the Philistine army this very day to the birds of the air and to the wild animals of the earth, so that all the earth may know that there is a God in Israel, ⁴⁷ and that all this assembly may know that the Lord does not save by sword and spear; for the battle is the Lord’s and he will give you into our hand.’
