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?' 26 But if we say, 'From man,' we are afraid of the crowd, for they all hold that John was a prophet." 27 So they answered Jesus, "We do not know." And he said to them, "Neither will I tell you by what authority I do these things.
28 "What do you think? A man had two sons. And he went to the first and said, 'Son, go and work in the vineyard today.'

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.
Commentary on Matthew 21:28-32
(Read Matthew 21:28-32)
Parables which give reproof, speak plainly to the offenders, and judge them out of their own mouths. The parable of the two sons sent to work in the vineyard, is to show that those who knew not John's baptism to be of God, were shamed by those who knew it, and owned it. The whole human race are like children whom the Lord has brought up, but they have rebelled against him, only some are more plausible in their disobedience than others. And it often happens, that the daring rebel is brought to repentance and becomes the Lord's servant, while the formalist grows hardened in pride and enmity.
