Matthew 22:7 - Joseph Benson’s Commentary on the Old and New Testaments

And when the king heard thereof, he was wroth Inasmuch as “the invitation to the marriage-feast of his son, sent by this king to his supposed friends, was the highest expression of his regard for them, and the greatest honour that could be done to them; therefore, when they refused it for such trifling reasons, and were so savagely ungrateful as to beat, and wound, and kill the servants who had come with it, it was justly viewed as a most outrageous affront, an injury that deserved the severest punishment.” Accordingly the king resented it exceedingly, and sent forth his armies, and destroyed those murderers, &c. This branch of the parable plainly predicted the destruction of the Jews by the Roman armies, called God's armies, because they were appointed by him to execute vengeance upon that once favourite, but now rebellions people. It is justly observed here by Dr. Doddridge, that “this clause must be supposed to come in by way of prolepsis, or anticipation; for it is plain there could not be time before the feast already prepared was served up, to attempt an execution of this kind.”
