Matthew 24:20 in the King James Version
But pray ye that your flight be not in the winter, neither on the sabbath day:
Context
19 But woe to those who are with child and to nursing mothers in those days!
20 Pray that your flight will not be in the winter nor on a Sabbath,
21 for then there will be great suffering, such as has not been from the beginning of the world until now, no, nor ever will be.
