1 Samuel 17:20-27

Early in the morning David left the flock in the care of a shepherd, loaded up and set out, as Jesse had directed. He reached the camp as the army was going out to its battle positions, shouting the war cry. Israel and the Philistines were drawing up their lines facing each other. David left his things with the keeper of supplies, ran to the battle lines and asked his brothers how they were. As he was talking with them, Goliath, the Philistine champion from Gath, stepped out from his lines and shouted his usual defiance, and David heard it. Whenever the Israelites saw the man, they all fled from him in great fear. Now the Israelites had been saying, “Do you see how this man keeps coming out? He comes out to defy Israel. The king will give great wealth to the man who kills him. He will also give him his daughter in marriage and will exempt his family from taxes in Israel.” 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?” They repeated to him what they had been saying and told him, “This is what will be done for the man who kills him.”
