Revelation 3:3 3 Remember therefore how thou hast received and heard, and hold fast, and repent. If therefore thou shalt not watch, I will come on thee as a thief, and thou shalt not know what hour I will come upon thee. The inverse of this would read “If thou shalt watch, thou shalt know what hour I will come upon thee”. And those holier than thous don't bother to learn that no man knows the day or hour is an idiom for Feast of Trumpets because they have to wait for two people to confirm the sighting of the moon.
