Matthew 24:20-22

Pray that your flight [from persecution and suffering] will not be in winter, or on a Sabbath [when Jewish laws prohibit travel]. For at that time there will be a great tribulation (pressure, distress, oppression), such as has not occurred since the beginning of the world until now, nor ever will [again]. [Dan 12:1; Joel 2:2] And if those days [of tribulation] had not been cut short, no human life would be saved; but for the sake of the elect (God’s chosen ones) those days will be shortened.
