21 Then let those who are in Judea flee to the mountains. Let those who are in the midst of her depart. Let those who are in the country not enter therein.

Then let them which are in Judaea flee to the mountains,.... See Gill on Matthew 24:16.
And let them which are in the midst of it; either of Judea, as the preceding clause seems to direct the sense; or in Jerusalem, and which indeed was in the midst of Judea; and this sense is favoured by the Persic version, which renders it, "within the city"; let them go out of it, as the Christians did to Pella, Mount Libanus, and other places:
and let not them that are in the countries; either foreign countries, or in towns and villages;
enter thereinto: either into Judea, or into Jerusalem; contrary to this advice, they came from all countries to the feast of the passover at Jerusalem, and were there shut up by the siege and destroyed (c).
(c) Joseph. de Bello Jude. l. 7. c. 17.
Let them that are in the midst of it - Where Jerusalem stands (that is, they that are in Jerusalem) depart out of it, before their retreat is cut off by the uniting of the forces near the city, and let not them that are in the adjacent countries by any means enter into it.
