But they that are learned shall shine as the brightness of the firmament: and they that instruct many to justice, as stars for all eternity.

“For every prophecy, before its fulfilment, is to men [full of] enigmas and ambiguities. But when the time has arrived, and the prediction has come to pass, then the prophecies have a clear and certain exposition. And for this reason, indeed, when at this present time the law is read to the Jews, it is like a fable; for they do not possess the explanation of all things pertaining to the advent of the Son of God, which took place in human nature; but when it is read by the Christians, it is a treasure, hid indeed in a field, but brought to light by the cross of Christ, and explained, both enriching the understanding of men, and showing forth the wisdom of God and declaring His dispensations with regard to man, and forming the kingdom of Christ beforehand, and preaching by anticipation the inheritance of the holy Jerusalem, and proclaiming beforehand that the man who loves God shall arrive at such excellency as even to see God, and hear His word, and from the hearing of His discourse be glorified to such an extent, that others cannot behold the glory of his countenance, as was said by Daniel: "Those who do understand, shall shine as the brightness of the firmament, and many of the righteous as the stars for ever and ever."”

“Gabriel speaks to Daniel.… Therefore the most holy Gabriel foretold that the saints should shine like the stars: for his sacred name did witness to them, that they might understand the truth. Nor is a resurrection only declared for the martyrs but for all people, righteous and unrighteous, godly and ungodly, that every one may receive according to his desert. For God, says the Scripture, "will bring every work to judgment."”

“This body shall rise, but it will not abide in its present condition but as an eternal body. No longer will it, as now, need nourishment for life or stairs for its ascent, for it will become spiritual, a marvelous thing, beggaring description. "Then shall the just," it is said, "shine forth like the sun and the moon and like the splendor of the firmament." God, foreknowing human unbelief, has given to the smallest worms to emit from their bodies beams of light in the summer, that natural fluorescence might be a parable of what we expect.… He who makes the worm shine luminously will much more illumine the just person. Therefore we shall rise again, all with eternal bodies, though not all with like bodies. A just person will receive a heavenly body, to dwell worthily with the angels, whereas the sinner will receive an eternal body and so never be consumed, though it burn eternally in fire.”

“And they that be wise shall shine as the brightness of the firmament,.... That are wise, not in things natural and civil, but in things spiritual; who are wise unto salvation; that are wise to know themselves, their state and condition by nature; their impurity and impotence; the insufficiency of their own righteousness; the exceeding sinfulness of sin, and the dangerous circumstances they are in; that are wise to know Christ, and him crucified; to believe in him, and trust in him for everlasting life and salvation: these at the resurrection shall shine, both in body and soul; their bodies shall be fashioned like to the glorious body of Christ; their souls shall be filled with perfect light and knowledge, and be completely holy, without any sin upon them; and this light and glory that will be upon both soul and body will be like the brightness of the heavens when the sun is risen; yea, it will be like the brightness and glory of the sun itself, as our Lord affirms; having, as it seems, respect to this passage, Mat 13:43. Some render it, "they that instruct" (i); or make others wise, and so restrain it to ministers of the word; but the more general sense is best; and, besides, they are more particularly described in the next clause: and they that turn many to righteousness as the stars forever and ever; or, "that justify many" (k); that teach the doctrine of a sinner's free justification by the righteousness of Christ; that lead and direct souls sensible of sin, and of the weakness of their own righteousness, to the righteousness of Christ, as being that only which justifies before God; otherwise it is God alone that justifies men, by imputing the righteousness of his Son unto them: but these show men the way of justification, or that which God takes to justify sinners; and this being the principal doctrine of the GospeL, they are denominated from it; and no man deserves the name of a Gospel minister that does not preach it, though this is not all that they preach; they preach all other doctrines of the Gospel in connection with it, and also instruct men thus justified to live soberly, righteously, and godly: now, as these are stars in the church of Christ below, who receive their light from Christ the sun of righteousness, and communicate it to his people; so they will continue stars in the Millennium state, and appear exceeding glorious, having the glory of God and Christ upon them, and not only then, but to all eternity. These words are applied to the days of the Messiah by the Jews (l). (i) "erudiunt", Munster; "erudientes", Junius & Tremellius; "qui alios instituerint", Grotius. (k) "justificantes", Pagninus, Montanus, Junius & Tremellius; "qui justificaverint", Calvin, Piscator. (l) Shemot Rabba sect. 15. fol. 102. 4.”

“And they that be wise - Those who are thoroughly instructed in Christ's word and doctrine, shall shine - shall be eminently distinguished in the Christian Church by the holiness of their lives, and the purity of their creed. And they that turn many to righteousness - They who, by preaching Christ crucified among their brethren, shall be the means of converting them to the Christian faith; shall be as the stars - bright luminaries in the Gospel kingdom of Jesus Christ. This also may be applied to the case of holy and useful men, particularly the faithful ministers of the Gospel, in the day of judgment. See Jam 5:20 (note), Co1 15:41-42 (note).”

“Learned in the law of God and true wisdom, which consists in knowing and loving God. (Challoner) — Hebrew, “instructors.” — Instruct. Hebrew, “justify,” in the same sense. The Machabees and other priests, &c. who instructed people in the law, and stood up for its defence, may be meant. (Calmet) — “There is as much difference between a learned sanctity and a holy rusticity, as there is between heaven and the stars.” (St. Jerome) — Teachers, martyrs, and virgins are entitled to an aureola, or accidental reward, besides the essential beatitude. (Worthington) — Many. Th.[Theodotion?] and the Vulgate read, “and of the just many shall be like for an age and after.” (St. Jerome)”
