1 Samuel 17:24

20 So David got up early in the morning, left the flock with a keeper, loaded up, and set out as Jesse had instructed him. He reached the camp as the army was marching out to its position and shouting the battle cry.

21 And Israel and the Philistines arrayed in formation against each other.

22 Then David left his supplies in the care of the quartermaster and ran to the battle line. When he arrived, he asked his brothers how they were doing.

23 And as he was speaking with them, suddenly the champion named Goliath, the Philistine from Gath, came forward from the Philistines and shouted his usual words, which David also heard.

24 When all the men of Israel saw Goliath, they fled from him in great fear.

25 Now the men of Israel had been saying, “Do you see this man who keeps coming out to defy Israel? To the man who kills him the king will give great riches. And he will give him his daughter in marriage and exempt his father’s house from taxation in Israel.”

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

27 The people told him about the offer, saying, “That is what will be done for the man who kills him.”

28 Now when David’s oldest brother Eliab heard him speaking to the men, his anger burned against David. “Why have you come down here?” he asked. “And with whom did you leave those few sheep in the wilderness? I know your pride and wickedness of heart—you have come down to see the battle!”
