Jesus replied, "I have a question for you. If you tell me the answer, I'll tell you what kind of authority I have to do these things.
Where did John get his authority to baptize? Did he get it from heaven or from humans?" They argued among themselves, "If we say ‘from heaven,' he'll say to us, ‘Then why didn't you believe him?'
But we can't say ‘from humans' because we're afraid of the crowd, since everyone thinks John was a prophet."
Then they replied, "We don't know." Jesus also said to them, “Neither will I tell you what kind of authority I have to do these things.
