Mark 13:16 KJV

And let him that is in the field not turn back again for to take up his garment.
Mark 13:16, King James Version

In context

15 And let him that is on the housetop not go down into the house, neither enter therein, to take any thing out of his house:

16 And let him that is in the field not turn back again for to take up his garment.

17 But woe to them that are with child, and to them that give suck in those days!
