And Jesus answered ... - Jesus was under no obligation to give them an answer.

They well knew by what authority he did this. He had not concealed his power in working miracles, and had not kept back the knowledge that he was the Messiah. He therefore referred them to a similar case - that of John the Baptist. He knew the estimation in which John was held by the people, and he took the wise in their own craftiness. Whatever answer they gave, he knew they Would convict themselves, and so they saw when they looked at the question. They reasoned correctly. If they should say that John received authority to baptize from God or from heaven, he would directly ask why they did not believe him. They professed to hear all the prophets. If they said, "Of men," they would be in danger, for all the people believed that John was a prophet.

The baptism of John - For an account of this, see Matthew 3. The word "baptism" here probably includes all his work. This was his principal employment; and hence he was called the Baptist, or the "Baptizer." But our Saviour's question refers "to his whole ministry." "The 'ministry of John' - his baptism, preaching, prophecies was it from God, or not?" If it was, then the inference was clear that Jesus was the Messiah, and then they might easily know by what authority he did those things.

From heaven - By divine authority, or by the command of God.

From men - By human authority.

I also will ask you one thing - Our Lord was certainly under no obligation to answer their question: he had already given them such proofs of his Divine mission as could not possibly be exceeded, in the miracles which he wrought before their eyes, and before all Judea; and, as they would not credit him on this evidence, it would have been in vain to have expected their acknowledgment of him on any profession he would make.

And Jesus answered and said unto them,.... Not by replying directly to their question, but by putting another question to them, whereby he escaped the snare he saw they laid for him:

I also will ask you one thing, word, or question,

which if ye tell me; honestly, and plainly answer to it,

I likewise will tell you by what authority I do these things: which was putting the thing upon such a foot, and in such a form, as they could not well object to; for Christ promises, that if they would return a plain answer to the question he had to put to them, and which was no unreasonable, nor impertinent one, he would thoroughly satisfy them in this point; and expressly declare his commission and authority, what it was, and from whence he had it. The question is as follows:

And Jesus answered and said unto them, I also will ask you {l} one thing, which if ye tell me, I in like wise will tell you by what authority I do these things.

(l) One thing, that is to say, I will ask you one thing first before I answer your questions.

21:24 I also will ask you one thing. A malicious question is often best answered by a question which will expose the questioners.

21:24 I will ask you one thing - Who have asked me many: The baptism, that is, the whole ministry of John, was it from heaven or from men? - By what authority did he act and teach? Did man or God give him that authority? Was it not God? But if so, the consequence was clear. For John testified that Jesus was the Christ.

24. And Jesus answered and said unto them, I also will ask you one thing, &c.

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.
