1 Samuel 17:8-9

8Goliath stood and shouted to the ranks of Israel, “Why do you come out and line up for battle? Am I not a Philistine, and are you not the servants of Saul? Choose a man and have him come down to me.

9If he is able to fight and kill me, we will become your subjects; but if I overcome him and kill him, you will become our subjects and serve us.”
