Daniel 12:3

“And they that be wise shall shine as the brightness of the firmament, etc.] 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…”

“they that be: Dan 11:33, Dan 11:35; Pro 11:30; Mat 24:45; Co1 3:10; Pe2 3:15 wise: or, teachers, Act 13:1; Eph 4:11; Heb 5:12 shine: Pro 4:18; Mat 13:43, Mat 19:28; Co1 15:40-42; Th1 2:19, Th1 2:20; Rev 1:20 turn: Jer 23:22; Luk 1:16, Luk 1:17; Joh 4:36; Phi 2:16, Phi 2:17; Jam 5:19, Jam 5:20 Daniel 12:4”
