1 Samuel 17:26-30

Then David said to the men who were standing by him, “What will be done for the man who kills this Philistine and rids Israel of the disgrace? For who is this uncircumcised Philistine, that he has dared to defy the armies of the living God?”

The people answered him in agreement with this statement, saying, “This is what will be done for the man who kills him.”

Now Eliab his oldest brother heard him when he spoke to the men; and Eliab’s anger burned against David and he said, “Why is it that you have come down? And with whom have you left those few sheep in the wilderness? I myself know your insolence and the wickedness of your heart; for you have come down in order to see the battle.”

But David said, “What have I done now? Was it not just a question?”

Then he turned away from him to another and said the same thing; and the people replied with the same words as before. David Kills Goliath
