Luke 20:7

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.

And Jesus said unto them, Neither tell I you by what authority I do these things.

Then began he to speak to the people this parable; A certain man planted a vineyard, and let it forth to husbandmen, and went into a far country for a long time.
