1 Samuel 17:23-32 (KJV)
23 And as he talked with them, behold, there came up the champion, the Philistine of Gath, Goliath by name, out of the armies of the Philistines, and spake according to the same words: and David heard them.
24 And all the men of Israel, when they saw the man, fled from him, and were sore afraid.
25 And the men of Israel said, Have ye seen this man that is come up? surely to defy Israel is he come up: and it shall be, that the man who killeth him, the king will enrich him with great riches, and will give him his daughter, and make his father’s house free in Israel.
26 And David spake to the men that stood by him, saying, What shall be done to the man that killeth this Philistine, and taketh away the reproach from Israel? for who is this uncircumcised Philistine, that he should defy the armies of the living God?
27 And the people answered him after this manner, saying, So shall it be done to the man that killeth him.
28 And Eliab his eldest brother heard when he spake unto the men; and Eliab’s anger was kindled against David, and he said, Why camest thou down hither? and with whom hast thou left those few sheep in the wilderness? I know thy pride, and the naughtiness of thine heart; for thou art come down that thou mightest see the battle.
29 And David said, What have I now done? Is there not a cause?
30 And he turned from him toward another, and spake after the same manner: and the people answered him again after the former manner.
31 And when the words were heard which David spake, they rehearsed them before Saul: and he sent for him.
32 And David said to Saul, Let no man’s heart fail because of him; thy servant will go and fight with this Philistine.
1 Samuel 17:45-51 (KJV)
45 Then 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 the Lord of hosts, the God of the armies of Israel, whom thou hast defied.
46 This day will the Lord deliver thee into mine hand; and I will smite thee, and take thine head from thee; and I will give the carcases of the host 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.
47 And all this assembly shall know that the Lord saveth not with sword and spear: for the battle is the Lord‘s, and he will give you into our hands.
48 And it came to pass, when the Philistine arose, and came, and drew nigh to meet David, that David hastened, and ran toward the army to meet the Philistine.
49 And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
50 So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David.
51 Therefore David ran, and stood upon the Philistine, and took his sword, and drew it out of the sheath thereof, and slew him, and cut off his head therewith. And when the Philistines saw their champion was dead, they fled.

11 When Saul and all Israel heard those words of the Philistine, they were dismayed, and greatly afraid.
