Mark
Chapters 13:31-37
English Revised Version
31Heaven and earth shall pass away: but my words shall not pass away.
32But of that day or that hour knoweth no one, not even the angels in heaven, neither the Son, but the Father.
33Take ye heed, watch and pray: for ye know not when the time is.
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.
