1 Samuel 17:40-47

40And 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.12

41And the Philistine came on and drew near unto David; and the man that bare the shield went before him.

42And when the Philistine looked about, and saw David, he disdained him: for he was but a youth, and ruddy, and of a fair countenance.

43And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.

44And 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.

45Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of Yhwh of Armies, the God of the armies of Israel, whom thou hast defied.

46This day will Yhwh deliver thee into mine hand; and I will smite thee, and take thine head from thee; and I will give the carcases of the army of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel.3

47And all this assembly shall know that Yhwh saveth not with sword and spear: for the battle is Yhwh's, and he will give you into our hands.
