Matthew 24:16-20

When the abomination of desolation appears, the Jews living in Jerusalem and Judea should flee immediately (cf. Luke 17:31; Revelation 12:14). His influence would extend far beyond Jerusalem. They must seek refuge in places where they can escape his persecution. They must not even take time to retrieve possessions from their houses as they flee. Pregnant women and nursing mothers will have a hard time because their physical conditions will limit their mobility. Weather would make flight harder in the winter, and observant Jews would seek to discourage travel on the Sabbath.
