1 Samuel 17:26-27
17:26 David asked the men who were standing near him, “What will be done for the man who strikes down this Philistine and frees Israel from this humiliation? For who is this uncircumcised Philistine, that he defies the armies of the living God?”
17:27 The soldiers told him what had been promised, saying, “This is what will be done for the man who can strike him down.”
