Matthew 21:28

²⁶  But if we shall say, Of men; we fear the people; for all hold John as a prophet.

²⁷  And they answered Jesus, and said, We cannot tell. And he said unto them, Neither tell I you by what authority I do these things.

²⁸  But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard.

²⁹  He answered and said, I will not: but afterward he repented, and went.

³⁰  And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.
