Matthew 21:25-27
21:25 Where did John’s baptism come from? From heaven or from people?” They discussed this among themselves, saying, “If we say, ‘From heaven,’ he will say, ‘Then why did you not believe him?’
21:26 But if we say, ‘From people,’ we fear the crowd, for they all consider John to be a prophet.”
21:27 So they answered Jesus, “We don’t know.” Then he said to them, “Neither will I tell you by what authority I am doing these things.
