Luke 20:4

And spake unto him, saying, Tell us, by what authority doest thou these things? or who is he that gave thee this authority?

And he answered and said unto them, I will also ask you one thing; and answer me:

And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then believed ye him not?

But and if we say, Of men; all the people will stone us: for they be persuaded that John was a prophet.
