Daniel 12:8-10 NKJV
Although I heard, I did not understand. Then I said, “My lord, what shall be the end of these things?”
And he said, “Go your way, Daniel, for the words are closed up and sealed till the time of the end. Many shall be purified, made white, and refined, but the wicked shall do wickedly; and none of the wicked shall understand, but the wise shall understand.
