John Gill Commentary Matthew 21:40

"When therefore the lord of the vineyard shall come, what will he do unto those husbandmen?" — Matthew 21:40 (ASV)

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 spoke this parable.
