John Calvin on Matthew 22:7-8

7. But when the king heard it. This punishment is mentioned by Matthew alone; for Luke makes no mention of any outrage committed on the servants. Both concur in stating, that those who did not come at the appointed time were shut out, and deprived of the honor of being present at the banquet. But this doctrine applies equally to us; for the same destruction which Christ denounces against the Jews awaits all the ungodly, who violently oppose the ministers of the Gospel. Those who are so entirely occupied with earthly cares, as to set no value on the divine invitation, will at length perish miserably in famine and want; and therefore, whenever God calls us, let us be prepared and ready to follow.
