1 Samuel 17:23-30
English Standard Version
24All the men of Israel, when they saw the man, fled from him and were much afraid.
25And the men of Israel said, "Have you seen this man who has come up? Surely he has come up to defy Israel. And the king will enrich the man who kills him with great riches and will give him his daughter and make his father 's house free in Israel."
26And David said to the men who stood by him, "What shall be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should defy the armies of the living God?"
27And the people answered him in the same way, "So shall it be done to the man who kills him."
28Now Eliab his eldest brother heard when he spoke to the men. And Eliab 's anger was kindled against David, and he said, "Why have you come down? And with whom have you left those few sheep in the wilderness? I know your presumption and the evil of your heart, for you have come down to see the battle."
29And David said, "What have I done now? Was it not but a word?"
30And he turned away from him toward another, and spoke in the same way, and the people answered him again as before.
