23 And when he entered the temple, the chief priests and the elders of the people came up to him as he was teaching, and said, "By what authority are you doing these things, and who gave you this authority?" 24 Jesus answered them, "I also will ask you one question, and if you tell me the answer, then I also will tell you by what authority I do these things. 25 The baptism of John, from where did it come? From heaven or from man?" And they discussed it among themselves, saying, "If we say, 'From heaven,' he will say to us, 'Why then did you not believe him?'

Commentary on Matthew 21:23-27
(Read Matthew 21:23-27)
As our Lord now openly appeared as the Messiah, the chief priests and scribes were much offended, especially because he exposed and removed the abuses they encouraged. Our Lord asked what they thought of John's ministry and baptism. Many are more afraid of the shame of lying than of the sin, and therefore scruple not to speak what they know to be false, as to their own thoughts, affections, and intentions, or their remembering and forgetting. Our Lord refused to answer their inquiry. It is best to shun needless disputes with wicked opposers.
