Matthew 24:15: “When" [The beginning of The Great Tribulation period] "ye" [Peter, James, John and Andrew] "therefore shall see The Abomination of desolation, spoken of by Daniel the prophet, stand in the holy place," [The daily sacrifice taken away/The Two Witnesses killed] "(whoso readeth, let him understand:)”
Matthew 24:16: “Then" [When The Two Witnesses are killed (the daily sacrifice taken away) and the abomination of desolation is set-up] "let them which be in Judaea" [The followers of Christ/God’s people] "flee into the mountains:”
Matthew 24:17: “Let him" [The believers/God's people] "which is on the housetop not come down to take any thing out of his house:”
Matthew 24:18: “Neither let him which is in the field return back to take his clothes.”
Matthew 24:19: “And woe unto them that are with child, and to them that give suck in those days!”
Matthew 24:20: “But pray ye that your flight be not in the winter, neither on the sabbath day:”
Matthew 24:21: “For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.”
Matthew 24:22: “And except those days" [The Great Tribulation; the time period from the setting up of The Abomination of desolation until the end (the coming of Christ)] "should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.”
