24 Jesus answered them, I also will ask you a question, and if you give Me the answer, then I also will tell you by what power of authority I do these things.
25 The baptism of John–from where was it? From heaven or from men? And they reasoned and argued with one another, If we say, From heaven, He will ask us, Why then did you not believe him?
26 But if we say, From men–we are afraid of and must reckon with the multitude, for they all regard John as a prophet.
27 So they answered Jesus, We do not know. And He said to them, Neither will I tell you by what power of authority I do these things.
28 What do you think? There was a man who had two sons. He came to the first and said, Son, go and work today in the vineyard.
29 And he answered, I will not; but afterward he changed his mind and went.
30 Then the man came to the second and said the same [thing]. And he replied, I will [go], sir; but he did not go.
