Mark 13:14-16

14“But when you see the abomination of desolation standing [in the temple sanctuary] where it ought not to be (let the reader understand) then those who are in Judea must flee to the mountains.

15Whoever is on the housetop must not go down [to enter the house], or go inside to take anything out of his house;

16whoever is in the field must not turn back to get his coat.
