201 It happened on one of those days, as he was teaching the people in the temple and preaching the Good News, that the [1]priests and scribes came to him with the elders. 2 They asked him, “Tell us: by what authority do you do these things? Or who is giving you this authority?” 3 He answered them, “I also will ask you one question. Tell me: 4 the baptism of John, was it from heaven, or from men?” 5 They reasoned with themselves, saying, “If we say, ‘From heaven,’ he will say, ‘Why didn’t you believe him?’ 6 But if we say, ‘From men,’ all the people will stone us, for they are persuaded that John was a prophet.” 7 They answered that they didn’t know where it was from.

Commentary on Luke 20:1-8
(Read Luke 20:1-8)
Men often pretend to examine the evidences of revelation, and the truth of the gospel, when only seeking excuses for their own unbelief and disobedience. Christ answered these priests and scribes with a plain question about the baptism of John, which the common people could answer. They all knew it was from heaven, nothing in it had an earthly tendency. Those that bury the knowledge they have, are justly denied further knowledge. It was just with Christ to refuse to give account of his authority, to those who knew the baptism of John to be from heaven, yet would not believe in him, nor own their knowledge.
