1 Samuel 17:20-26

So David got up early in the morning, left the flock with someone to keep it, loaded up, and set out as Jesse had instructed him. He arrived at the perimeter of the camp as the army was marching out to its battle formation shouting their battle cry. Israel and the Philistines lined up in battle formation facing each other. 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. While he was speaking with them, suddenly the champion named Goliath, the Philistine from Gath, came forward from the Philistine battle line and shouted his usual words, which David heard. When all the Israelite men saw Goliath, they retreated from him terrified. Previously, an Israelite man had declared: “Do you see this man who keeps coming out? He comes to defy Israel. The king will make the man who kills him very rich and will give him his daughter. The king will also make the household of that man’s father exempt from paying taxes in Israel.” David spoke to the men who were standing with him: “What will be done for the man who kills that Philistine and removes this disgrace from Israel? Just who is this uncircumcised Philistine that he should defy the armies of the living God? ”
