Matthew 24:20-22

Revised Standard Version

²⁰ Pray that your flight may not be in winter or on a sabbath. ²¹ For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be. ²² And if those days had not been shortened, no human being would be saved; but for the sake of the elect those days will be shortened.
