Matthew 22:1 - Joseph Benson’s Commentary on the Old and New Testaments

Jesus spake unto them again by parables That is, spake with reference to what had just passed: for this parable is closely connected with that of the vineyard, delivered at the close of the preceding chapter. And as our Lord had in that foretold the approaching ruin of the Jewish place and nation, he goes on in this to vindicate God's mercy and justice in the rejection of that people and the calling of the Gentiles; admonishing the latter, at the same time, of the necessity of holiness, and showing that if they remained destitute of it, they would meet with the same severity of judgment which had befallen the disobedient Jews.
