And they that be wise - This is the language which, in the Scriptures, is employed to denote the pious, or those who serve God and keep his commandments. See the book of Proverbs, passim. True religion is wisdom, and sin is folly, and they who live for God and for heaven are the truly wise. The meaning is, that they have chosen the path which true wisdom suggests as that in which man should walk, while all the ways of sin are ways of folly. The language used here is expressive of a general truth, applicable in itself to all the righteous at all times, and nothing can be inferred from the term employed as to what was designed by the angel.
Shall shine as the brightness of the firmament - As the sky above us. The image is that of the sky at night, thick set with bright and beautiful stars. No comparison could be more striking. The meaning would seem to be, that each one of the righteous will be like a bright and beautiful star, and that, in their numbers, and order, and harmony, they would resemble the heavenly constellations at night. Nothing can be more sublime than to look on the heavens in a clear night, and to think of the number and the order of the stars above us as an emblem of the righteous in the heavenly world. The word rendered firmament means, properly, expanse, or what is spread out, and it is applied to the sky as it appears to be spread out above us.
And they that turn many to righteousness - Referring to those who would be instrumental in converting men to the worship of the true God, and to the ways of religion. This is very general language, and might be applied to any persons who have been the means of bringing sinners to the knowledge of the truth. It would apply in an eminent degree to ministers of the gospel who were successful in their work, and to missionaries among the pagan. From the mere language, however, nothing certain can be argued as to the original reference as used by the angel, and it seems to have been his intention to employ language so general that it might be applied to all, of all ages and countries, who would be instrumental in turning men to God.
As the stars - As the stars that are distinguished by their size and luster in the firmament. In the former part of the verse, when speaking of those who were “wise,” the design seems to be to compare them to the sky as it appears, set over with innumerable stars, and in their numbers and groupings constituting great beauty; in this member of the sentence the design seems to be to compare these who are eminent in converting men, to the particular beautiful and bright stars that strike us as we look on the heavens - those more distinguished in size and splendor, and that seem to lead on the others. The meaning is, that amidst the hosts of the saved they will be conspicuous, or they will be honored in proportion to their toils, their sacrifices, and their success.
Forever and ever - To all eternity. This refers to those who shall turn many to righteousness; and the meaning is, that they shall continue thus to be distinguished and honored to all eternity.
