Matthew 21:23-27 New King James Version (NKJV)

24 But Jesus answered and said to them, “I also will ask you one thing, which if you tell Me, I likewise will tell you by what authority I do these things: 25 The baptism of John—where was it from? From heaven or from men?”
And they reasoned among themselves, saying, “If we say, ‘From heaven,’ He will say to us, ‘Why then did you not believe him?’ 26 But if we say, ‘From men,’ we fear the multitude, for all count John as a prophet.” 27 So they answered Jesus and said, “We do not know.”
And He said to them, “Neither will I tell you by what authority I do these things.
