DAN 12:3

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).

12:3 Those who are wise know their God (cp. 1:4, 17; 8:25; 9:22, 25; 11:32-35; 12:10). • To shine is a familiar metaphor for life, purity, righteousness, and glory.

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.
