Rapture according to Mid-Tribulation Theory

I am working on writing a blog post about the rapture and am curious about the different theories of the rapture. Could someone explain to me the Mid-Tribulation Rapture theory and show some supporting verses for it, as given by those who support this theory? I previously asked about the Pre-Tribulation theory [here](https://christianity.stackexchange.com/questions/57792/rapture-according-to-pre-trib-theory) .
