Matthew 24:20-22

New Revised Standard Version Catholic Edition

²⁰ Pray that your flight may not be in winter or on a sabbath. ²¹ For at that time there will be great suffering, 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 cut short, no one would be saved; but for the sake of the elect those days will be cut short.
