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.
25. The baptism of John—meaning his whole mission and ministry, of which baptism was the proper character.
whence was it? from heaven, or of men?—What wisdom there was in this way of meeting their question will best appear by their reply.
If we shall say, From heaven; he will say unto us, Why did ye not then believe him?—"Why did ye not believe the testimony which he bore to Me, as the promised and expected Messiah?" for that was the burden of John's whole testimony.
