Matthew 24:16 - Wesley's Explanatory Notes

Then let them who are in Judea flee to the mountains — So the Christians did, and were preserved. It is remarkable that after the Romans under Cestus Gallus made their first advances toward Jerusalem, they suddenly withdrew again, in a most unexpected and indeed impolitic manner. This the Christians took as a signal to retire, which they did, some to Pella, and others to Mount Libanus.
