1 Samuel 17:10, 26, 36

And the Philistine said, “I defy the ranks of Israel this day. Give me a man, that we may fight together.”

And 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?”

Your servant has struck down both lions and bears, and this uncircumcised Philistine shall be like one of them, for he has defied the armies of the living God.”
