1 Samuel 17:23-26

As he was talking with them, behold, the champion, the Philistine of Gath named Goliath, was coming up from the army of the Philistines, and he spoke these same words again; and David heard him. When the men of Israel all saw the man, they fled from him, and were very frightened. The men of Israel said, “Have you seen this man who is coming up? Surely he is coming up to defy Israel. The king will reward the man who kills him with great riches, and will give him his daughter [in marriage] and make his father’s house (family) free [from taxes and service] in Israel.” Then David spoke to the men who were standing by him, “What will be done for the man who kills this Philistine and removes the disgrace [of his taunting] from Israel? For who is this uncircumcised Philistine that he has taunted and defied the armies of the living God?”
