Mark 13:32-37

³²But of that day or that hour knoweth no one, not even the angels in heaven, neither the Son, but the Father.i

³³Take ye heed, watch and pray: for ye know not when the time is.j

³⁴[It 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;k

³⁶lest coming suddenly he find you sleeping.

³⁷And what I say unto you I say unto all, Watch.
