John Lightfoot on Matthew 19:28

[Ye that have followed me, in the regeneration.] That the world is to be renewed at the coming of the Messias, and the preaching of the gospel, the Scriptures assert, and the Jews believe; but in a grosser sense, which we observe at chapter 24. Our Saviour, therefore, by the word regeneration, calls back the mind of the disciples to a right apprehension of the thing; implying that renovation, concerning which the Scripture speaks, is not of the body or substance of the world; but that it consists in the renewing of the manners, doctrine, and a dispensation conducing thereunto: men are to be renewed, regenerated,--not the fabric of the world. This very thing he teaches Nicodemus, treating concerning the nature of the kingdom of heaven, John 3:3.

[When the Son of man shall sit upon the throne of his glory, ye also shall sit.] These words are fetched out of Daniel, chapter 7:9,10; which words I wonder should be translated by the interpreters, Aben Ezra, R. Saadia, and others, as well Jews as Christians, thrones were cast down. R. Solomon the Vulgar, and others, read it righter, thrones were set up: where Lyranus thus, "He saith thrones in the plural number, because not only Christ shall judge, but the apostles, and perfect men, shall assist him in judgment, sitting upon thrones." The same way very many interpreters bend the words under our hands, namely, that the saints shall at the day of judgment sit with Christ, and approve and applaud his judgment. But, 1. besides, that the scene of the last judgment, painted out in the Scripture, does always represent as well the saints as the wicked standing before the tribunal of Christ, Matthew 25:32, 2 Corinthians 5:10, &c.; we have mention here only of "twelve thrones." And, 2, we have mention only of judging the "twelve tribes of Israel." The sense, therefore, of the place may very well be found out by weighing these things following:

I. That those thrones set up in Daniel are not to be understood of the last judgment of Christ, but of his judgment in his entrance upon his evangelical government, when he was made by his Father chief ruler, king, and judge of all things: Psalm 2:6, Matthew 28:18, John 5:27. For observe the scope and series of the prophet, that, after the four monarchies, namely, the Babylonian, the Medo-Persian, the Grecian, and the Syro-Grecian, which monarchies had vexed the world and the church by their tyranny, were destroyed, the kingdom of Christ should rise, &c. Those words, "The kingdom of heaven is at hand," that judiciary scene set up Revelation 4 and 5, and those thrones Revelation 20:1, &c. do interpret Daniel to this sense.

II. The throne of glory, concerning which the words before us are, is to be understood of the judgment of Christ to be brought upon the treacherous, rebellious, wicked people. We meet with very frequent mention of the coming of Christ in his glory in this sense; which we shall discourse more largely of at chapter 24.

III. That the sitting of the apostles upon thrones with Christ is not to be understood of their persons, it is sufficiently proved; because Judas was now one of the number: but it is meant of their doctrine: as if he had said, "When I shall bring judgment upon this most unjust nation, then our doctrine, which you have preached in my name, shall judge and condemn them." See Romans 2:16.

Hence it appears that the gospel was preached to all the twelve tribes of Israel before the destruction of Jerusalem.
