Luke 20:2-6

and they declared, saying to Him, “Tell us by what authority You are doing these things, or who is the one who gave You this authority?”

But He replied to them, “I will also ask you a question, and you tell Me:

Was the baptism of John from heaven or from men?”

They discussed among themselves, saying, “If we say, ‘From heaven,’ He will say, ‘Why did you not believe him?’

But if we say, ‘From men,’ all the people will stone us to death, since they are convinced that John was a prophet.”
