'Wicked' in the Bible

Because of the transgression [of God’s people—their irreverence and ungodliness] the host will be given over to the wicked horn, along with the regular sacrifice; and righteousness and truth will be flung to the ground, and the horn will do as it pleases [by divine permission] and prosper.

Many 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.
