23 When Jesus returned to the Temple and began teaching, the leading priests and elders came up to him. They demanded, "By what authority are you doing all these things? Who gave you the right?" 24 "I'll tell you by what authority I do these things if you answer one question," Jesus replied. 25 "Did John's authority to baptize come from heaven, or was it merely human?" They talked it over among themselves. "If we say it was from heaven, he will ask us why we didn't believe John. 26 But if we say it was merely human, we'll be mobbed because the people believe John was a prophet." 27 So they finally replied, "We don't know." And Jesus responded, "Then I won't tell you by what authority I do these things.
28 "But what do you think about this? A man with two sons told the older boy, 'Son, go out 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.
