1 Samuel 17:8-9

8And Goliath stood and shouted to the ranks of Israel, “Why do you come out and array yourselves for battle? Am I not a Philistine, and are you not servants of Saul? Choose one of your men and have him come down against me. 9If he is able to fight me and kill me, then we will be your servants. But if I prevail against him and kill him, then you shall be our servants and work for us.”
