But of that day and that hour knoweth no man,
no, not the angels which are in heaven,
neither the Son, but the Father.
Take ye heed, watch and pray:
for ye know not when the time is.
For the Son of Man is as a man taking a far journey,
who left his house, and gave authority to his servants,
and to every man his work,
and commanded the porter to watch.
Watch ye therefore: for ye know
not when the master of the house cometh,
at even, or at midnight, or at the cockcrowing,
or in the morning:
Lest coming suddenly
he find you sleeping.
Mark 13:32-36
