22:59 And after about an hour still another insisted, “Certainly this man was with him, because he too is a Galilean.”
22:60 But Peter said, “Man, I don’t know what you’re talking about!” At that moment, while he was still speaking, a rooster crowed.

18:26 One of the high priest’s slaves, a relative of the man whose ear Peter had cut off, said, “Did I not see you in the orchard with him?”
18:27 Then Peter denied it again, and immediately a rooster crowed.
