Matthew 24:19 YLT

¹⁷  he on the house-top -- let him not come down to take up any thing out of his house;

¹⁸  and he in the field -- let him not turn back to take his garments.

¹⁹  'And wo to those with child, and to those giving suck in those days;

²⁰  and pray ye that your flight may not be in winter, nor on a sabbath;

²¹  for there shall be then great tribulation, such as was not from the beginning of the world till now, no, nor may be.
