Daniel 12:8-10

8As for me, I heard, but I did not understand; so I said, “My lord, what will be the outcome of these things?”

9And the angel said, “Go your way, Daniel, for the words are concealed and sealed up until the end of time.

10Many will be purged, purified (made white) and refined, but the wicked will behave wickedly. None of the wicked shall understand, but those who are [spiritually] wise will understand.
