Mark
Chapters 13:34-37
Revised Version 1885
34It is as when a man, sojourning in another country, having left his house, and given authority to his servants, to each one his work, commanded also the porter to watch.
35Watch therefore: for ye know not when the lord of the house cometh, whether at even, or at midnight, or at cockcrowing, or in the morning;
36lest coming suddenly he find you sleeping.
37And what I say unto you I say unto all, Watch.
