John Gill Commentary Luke 14:16

"But he said unto him, A certain man made a great supper; and he bade many:" — Luke 14:16 (ASV)

Then he said to him
That is, Jesus, as the Syriac, Persic, and Ethiopic versions express it; he said to the man who was so affected with the happiness of those who shall share in the provisions of the Messiah's kingdom;

a certain man made a great supper :
by which is not meant the Lord's supper, which had not yet been instituted; nor the supper of the Lamb, which will be at the end of the world; but the Gospel dispensation, which was now taking place, and its provisions in the word and ordinances: and which is called a "supper" because it was made in the end of the world, in the last days: and a "great" one because of its maker, the King of kings, and Lord of lords; and its matter, a variety of rich provisions, a feast of fat things, an entertainment consisting of the greatest dainties, and most delightful food;

and on account of the number of invited guests, all people, every creature, to whom the outward ministration of the Gospel comes; and those who are properly guests that come are a great number which no man can number; as well as because of its cost and charges to the maker, though it is all free to the guests; and likewise because of the circumstances of exceeding great joy and pleasure that attend it; to which may be added its long duration, even from the first to the second coming of Christ.

And bade many .
This first bidding more especially respects the Jews, who are said to be "many" in reference to the promise made to Abraham, that his seed should be as the stars of the heavens, and as the sand of the sea; and to set off the magnificence of the feast; and in distinction from all the world, and every creature, which were afterwards put into the Gospel commission:

a foundation was laid for this supper in eternity, in the purposes, counsel, and covenant of God; and many prophecies concerning it were given out from the beginning; and sacrifices and ordinances were instituted as emblematical of it, and to lead on to it, and give notice of it.
