Sent his servant - An invitation had been sent before, but this servant was sent at the time that the supper was ready. From this it would seem that it was the custom to announce to those invited just the time when the feast was prepared. The custom here referred to still prevails in Palestine. Dr. Thomson ("The Land and the Book," vol. i. p. 178) says: "If a sheikh, beg, or emeer invites, he always sends a servant to call you at the proper time. This servant often repeats the very formula mentioned in Luke 14:17; Tefŭddŭlû, el 'asha hâder. Come, for the supper is ready. The fact that this custom is mainly confined to the wealthy and to the nobility is in strict agreement with the parable, where the certain man who made the great supper and bade many is supposed to be of this class. It is true now, as then, that to refuse is a high insult to the maker of the feast, nor would such excuses as those in the parable be more acceptable to a Druse emeer than they were to the lord of this 'great supper.'"

Sent his servant - Messengers are sent to invite the guests to a Hindoo feast; when not only relations, but all persons of the same division of caste in the neighborhood, are invited. A refusal to attend is considered as a great affront.

And sent his servant at supper time,.... Either John the Baptist, the harbinger and forerunner of Christ, who declared that the kingdom of heaven, or the Gospel dispensation, was at hand; and exhorted the people to believe in Christ that should come after him; or Christ himself, who is God's servant as man, of his choosing and appointing, and whom he sent in the fulness of time in the form of a servant, as the minister of the circumcision, to the lost sheep of the house of Israel, and to call sinners to repentance; or servant may be put for servants, since in Matthew 22:3 mention is made of more; and so the Persic version here; which parable bears some likeness to this, if it is not the same; and may design the apostles of Christ, who were the servants of the most high God, and the ministers of Christ, who were first sent by him to preach the Gospel to the Jews, and to them only for a while:
to say to them that were bidden, come: this call, or invitation, was not the internal call, which is a fruit of love, and by grace, and of mighty power; to special blessings, grace, and glory; and is irresistible, effectual, and unchangeable: but external, to outward ordinances: and is often slighted and neglected; and is sometimes of persons who are neither chosen, nor sanctified, nor saved:
for all things are now ready; the Syriac version adds, "for you": righteousness, pardon of sin, peace, and reconciliation, sin put away by the sacrifice of Christ, redemption obtained, and life and salvation secured; which shows the perfection of the present dispensation, and the large provisions of the Gospel, to which nothing is, or can be brought to be added to them, or qualify for them.

supper-time . . . all now ready--pointing undoubtedly to the now ripening preparations for the great Gospel call. (See on Matthew 22:4.)
