Mark 13:14-16

14But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that are in Judaea flee to the mountains: 15And let him that is on the housetop not go down into the house, neither enter it, to take any thing out of his house: 16And let him that is in the field not turn back again to take up his garment.
