Albert Barnes' Bible Commentary
Daniel 12:10
Many shall be purified - In future times. That is, as the connection would seem to require, there will be a system introduced by which many will become purified, and made holy. Daniel might hope and expect that under the arrangements which God would make, many of the human race would be cleansed from sin. To what he would apply this we cannot determine, but it is a great truth of immense importance in regard to the human family, that, before the “end,” or the consummation, “many” will be made holy.
And made white - White is the emblem of innocence or purity, and hence, the term is so often applied to the righteous. “They have washed their robes, and made them white in the blood of the Lamb,” “they shall walk before me in white,” etc. Hence, the angels are represented as appearing in white raiment. The meaning here is, that many on the earth would be made holy before the end would come. The mind of Daniel was thus directed onward to one of the most glorious truths pertaining to future times - that multitudes of the human race would be redeemed, and would be prepared for a holy heaven.
And tried - Tried as in a furnace; that is, they will be subjected to persecutions, and to various other forms of suffering, that will test the strength of their faith, and the nature of their religion. This language, also, is of a general character, and would in itself apply to the times of Antiochus, but it is also fitted to describe what would occur in other ages. Perhaps the meaning is, that it would be a prominent thing in the future, in introducing the triumphs of religion; and in preparing the people of God for heaven, that they would be subjected to various forms of trial. There have been facts enough of this kind in the history of the church to justify this description, and to show that it would be a marked feature in spreading religion on the earth, that its friends would be persecuted. “But the wicked shall do wickedly.” They will continue to do wickedly. Notwithstanding all the judgments that will come upon men; notwithstanding all that will be done to purify the people of God, and, notwithstanding the fact that “many” will be of a different character - will be “purified and made white, and tried,” yet it will be a truth still, that there will be wicked men upon the earth, and that they will act out their nature.
This remark seems to have been thrown in by the angel to prevent the impression which Daniel might possibly get from what was said, not only that the true religion would generally prevail, but that wickedness would wholly cease in the earth. Such a time, perhaps, we are not authorized to look for; while we may hope and believe that there will be a period when the worship of God will pervade the world, and will supersede all other forms of worship, yet we have no reason to expect that every individual of the human family at any one time will be converted, and that none of the remains of the apostasy will be seen on the earth. There will be wicked men still, and they will act out their nature, despite all that is done to save them, and despite the fact that religion will have the ascendency in the hearts and lives of the great mass of mankind. For an illustration of this, see the notes at Revelation 9:20; notes at Revelation 20:7.
And none of the wicked shall understand - This, also, is a general declaration. It means, that none of the wicked would understand the import of these prophecies, or the true nature of religion. Their depravity of heart would prevent it; their purpose to lead a wicked life would so cloud their understandings, and pervert their moral judgments, that they would have no correct appreciation of the government of God, and the nature of the Divine plans and dispensations. Compare the notes at 1 Corinthians 2:14. The fact here asserted has been always true, and always will be, that sin prevents a clear perception of Divine truth, and that wicked men have no appropriate views of the plans and purposes of God. To comprehend religion aright a man needs a pure heart; and no one under the influence of depraved feelings, and corrupt propensities and appetites, can expect to have a just appreciation of what is good. Doubtless it will be found to be true in the days of millennial glory, when the true religion shall spread over the world, and when the earth shall be filled with light, that there will be wicked men who will have no correct understanding of the nature of religion, and whose minds will be blind to all the evidences of the truth of revelation which shall be diffused around them. No man, unless he is converted, has any proper conception of the beauty of religion.
But the wise shall understand - They who serve God and love him, and who, therefore, come under the denomination of the truly wise. See the notes at Daniel 12:3. The meaning is, that religion - the love of God and a pure heart - will qualify them to perceive the import of Divine truth; to appreciate what is revealed, and to obtain a just view of passing events - or to “understand the signs of the times.” Humble and sincere piety - a heart and mind made pure and clear by the influence of Divine truth - is the best preparation for understanding the works and ways of God. Compare the notes at 1 Corinthians 2:9, 1 Corinthians 2:14.
