4 A champion named Goliath, who was from Gath, came out of the Philistine camp. His height was six cubits and a span. 5 He had a bronze helmet on his head and wore a coat of scale armour of bronze weighing five thousand shekels; 6 on his legs he wore bronze greaves, and a bronze javelin was slung on his back. 7 His spear shaft was like a weaver’s rod, and its iron point weighed six hundred shekels. His shield bearer went ahead of him.

10 Then the Philistine said, “This day I defy the armies of Israel! Give me a man and let us fight each other.” 11 On hearing the Philistine’s words, Saul and all the Israelites were dismayed and terrified.

-1 Samuel 17:4-7, 10-11

23 As David was talking with his brothers, Goliath, the Philistine champion from Gath, stepped out from his lines and shouted his usual defiance, and David heard it.

-1 Samuel 17:23

26 David asked the men standing near him, “What will be done for the man who kills this Philistine and removes this disgrace from Israel? Who is this uncircumcised Philistine that he should defy the armies of the living God?”

-1 Samuel 17:26

32 David said to Saul, “Let no one lose heart on account of this Philistine; your servant will go fight him.” 

-1 Samuel 17:32

33 “You are not able to go outside against this Philistine and fight him; you are only a young man, and he has been a fighting man from his youth.” 

-1 Samuel 17:33

37 ‘The Lord who rescued me from the paw of the lion and the paw of the bear will rescue me from the hand of this Philistine.’ “ 

-1 Samuel 17:37

42 “He looked David over and saw that he was little more than a boy, glowing with health and handsome, and he despised him. 43 He said to David, ‘Am I a dog that you come at me with sticks?’ And the Philistine cursed David by his gods. 44 “Come here,” he said, “and I’ll give your flesh to the birds and the wild animals!’ “

-1 Samuel 17:42-44 

45 David said to the Philistine, “You come against me with sword and spear and javelin, but I come against you in the name of the LordAlmighty, the God of the armies of Israel, whom you have defied. 46 This day the Lord will deliver you into my hands, and I’ll strike you down and cut off your head. This very day I will give the carcasses of the Philistine army to the birds and the wild animals, and the whole world will know that there is a God in Israel. 

48 As the Philistine moved closer to attack him, David ran quickly toward the battle line to meet him. 49 Reaching into his bag and taking out a stone, he slung it and struck the Philistine on the forehead. The stone sank into his forehead, and he fell facedown on the ground.

-1 Samuel 17:45-46, 48-49
