1 Nevertheless as coming the tokens, behold, the days shall come, that they which dwell upon earth shall be taken in a great number, and the way of truth shall be hidden, and the land shall be barren of faith.
2 But iniquity shall be increased above that which now thou seest, or that thou hast heard long ago.
2 Esdras Chapter 6
26 And the men that are received shall see it, who have not tasted death from their birth: and the heart of the inhabitants shall be changed, and turned into another meaning.
The Pretribulational Rapture of the Church is clearly mentioned in II Esdras which is where the Apostles got the teaching from - see especially Oxford's translation where the phrase "Received" above is specifically, "Taken Up."
