Luke 20:4-8

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.”

And so they answered that they did not know where it came from.

And Jesus said to them, “Neither am I telling you by what authority I do these things.” Parable of the Vine-growers
