Mark 13:32-37

32 But of that day and [that] hour knoweth no man, no not the angels which are in heaven, neither the Son, but the Father.

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

34 [For the son of man is] as a man taking a long journey, who left his house, and gave authority to his servants, and to every man his work; and commanded the porter to watch.

35 Watch ye therefore: for ye know not when the master of the house cometh, at evening, or at midnight, or at the cock-crowing, or in the morning:

36 Lest coming suddenly, he should find you sleeping.

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