1 Samuel 17:22-25

22David left his things with the keeper of supplies, ran to the battle lines and asked his brothers how they were. 23As 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.

24Whenever the Israelites saw the man, they all fled from him in great fear.

25Now 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.”
