When the lord, therefore ... - Jesus then asked them a question about the proper way of dealing with those people.

The design of asking them this question was that they might condemn themselves, and admit the justice of the punishment that was soon to come upon them.

When the Lord therefore of the vineyard cometh,.... In a way of providence, to call these husbandmen to an account; not only for the fruit they were to bring to him; but for their barbarity to his servants, the prophets, time after time; and especially, for the inhuman usage and murder of his own son,

what will he do unto those husbandmen? This question is put to the chief priests, elders, and Scribes: and they themselves, who are designed hereby, are made judges in this case, just as the inhabitants of Jerusalem and men of Judah are, in Isaiah 5:4 which passage of Scripture our Lord had greatly in view when he spake this parable.

When the lord therefore of the vineyard cometh, what will he do unto those husbandmen?

21:40 When the lord therefore... cometh, what will he do? This question is addressed to the Jews, who seem to have been so carried away by the vivid description that they answered without seeing that they pronounced their own sentence. See Mt 21:41.

40. When the lord therefore of the vineyard cometh-This represents "the settling time," which, in the case of the Jewish ecclesiastics, was that judicial trial of the nation and its leaders which issued in the destruction of their whole state.

what will he do unto those husbandmen?

21:33-46 This parable plainly sets forth the sin and ruin of the Jewish nation; and what is spoken to convict them, is spoken to caution all that enjoy the privileges of the outward church. As men treat God's people, they would treat Christ himself, if he were with them. How can we, if faithful to his cause, expect a favourable reception from a wicked world, or from ungodly professors of Christianity! And let us ask ourselves, whether we who have the vineyard and all its advantages, render fruits in due season, as a people, as a family, or as separate persons. Our Saviour, in his question, declares that the Lord of the vineyard will come, and when he comes he will surely destroy the wicked. The chief priests and the elders were the builders, and they would not admit his doctrine or laws; they threw him aside as a despised stone. But he who was rejected by the Jews, was embraced by the Gentiles. Christ knows who will bring forth gospel fruits in the use of gospel means. The unbelief of sinners will be their ruin. But God has many ways of restraining the remainders of wrath, as he has of making that which breaks out redound to his praise. May Christ become more and more precious to our souls, as the firm Foundation and Cornerstone of his church. May we be willing to follow him, though despised and hated for his sake.
