Is the rapture taught anywhere else in the Bible besides Paul's writings?

Les explains that the rapture is a revelation of something totally different, yet all part of the same complex revelation. It is never referred to anywhere else in Scripture, which is why people have such a hard time contemplating it. He calls it a Pauline doctrine you won't find anywhere else in your Bible. In 1 Corinthians 15:51, Paul says, 'Behold, I show you a mystery'—a secret never before revealed. This mystery is that there will be one group of believers who are not going to die physically; they will be alive when everything comes to a culmination. Nowhere else is that ever hinted at in Scripture. So it is part of the mystery that at the end of the church age, a group of believers will be suddenly changed from here to there in a split second. Les notes it is hard to comprehend, and no wonder the unbeliever scoffs at it, because it takes faith to believe that Christ will leave glory, come to the atmosphere, the trumpet will sound, the archangel will shout, and all the dead believers of the church age will be raised and resurrected to meet the Lord in the air, and in a split second those still alive and remain will follow.
