I go, sir - This is all respect, complaisance, and professed, obedience; but he went not: he promised well, but did not perform. What a multitude of such are in the world, professing to know God, but denying him in their works! Alas! what will such professions avail, when God comes to take away the soul?

And he came to the second,.... The Scribes and Pharisees, by the ministry of John the Baptist, Christ, and his apostles also:

and said likewise; the same things as to the other son, the publicans and sinners; calling them into the Gospel dispensation, to hear the word, embrace truth, attend on ordinances, and labour in promoting the kingdom, and interest of the Messiah, whilst they had the light of the Gospel with them. Urging also the relation they stood in to God, as a part of the Jewish body; to whom, among other external privileges, the adoption belonged:

and he answered and said, I go, sir, and went not: the word "go" is not in the generality of the Greek copies; the phrase is only "I sir", though it is rightly enough supplied as to the sense. Beza says, it was in his most ancient copy; and so it is in the Arabic and Persic versions, and in Munster's Hebrew Gospel; though it is not in the Syriac and Ethiopic versions. So, the Scribes and Pharisees seemed pleased with the ministry of John for a while, and at first were forward to submit to his baptism, and were very inquisitive about the Messiah: yet, when he was declared in John's ministry, and by his own doctrine, and miracles, they refused to give in to the belief of him; they would neither enter into the Gospel kingdom, embrace the doctrines, and obey the commands of it themselves, nor suffer others to enter in; but, as much as in them lay, by their reproaches, menaces, and excommunications, deterred them from it. They, were like some other persons, who promise fair, and talk much of doing good works, but do none; teach the people to do them, but do not perform them themselves, though they would seem to do them; make great pretensions to them, boast of them, and trust in them; and therefore, of all men, ought to be careful to maintain them, and yet do the least.

And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.

21:28-31 A certain man had two sons. The two sons represent the priests, elders and scribes on the one hand, and the publicans and harlots, the sinners, on the other (Mt 21:31). Both classes were bidden to work in the Lord's vineyard. The publicans and sinners had refused, but repented at the preaching of John. The others professed to obey, but did not. The design of the parable is to show that the publicans and harlots, whom they so much despised, were morally superior to his questioners.

21:30 He answered, I go, sir: but went not - Just so did the scribes and Pharisees: they professed the greatest readiness and zeal in the service of God: but it was bare profession, contradicted by all their actions.

30. And he came to the second, and said likewise. And he answered and said, I go, sir-"I, sir." The emphatic "I," here, denotes the self-righteous complacency which says, "God, I thank thee that I am not as other men" (Lu 18:11).

and went not-He did not "afterward repent" and refuse to go; for there was here no intention to go. It is the class that "say and do not" (Mt 23:3)-a falseness more abominable to God, says Stier, than any "I will not."

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.
