'Revealed' in the Bible

and to give relief to you who are so distressed and to us as well when the Lord Jesus is revealed from heaven with His mighty angels in a flame of fire,

Let no one in any way deceive or entrap you, for that day will not come unless the apostasy comes first [that is, the great rebellion, the abandonment of the faith by professed Christians], and the man of lawlessness is revealed, the son of destruction [the Antichrist, the one who is destined to be destroyed],

And you know what restrains him now [from being revealed]; it is so that he will be revealed at his own [appointed] time.

Then the lawless one [the Antichrist] will be revealed and the Lord Jesus will slay him with the breath of His mouth and bring him to an end by the appearance of His coming.
