Mark 13:36 YLT

³⁴  as a man who is gone abroad, having left his house, and given to his servants the authority, and to each one his work, did command also the porter that he may watch;

³⁵  watch ye, therefore, for ye have not known when the lord of the house doth come, at even, or at midnight, or at cock-crowing, or at the morning;

³⁶  lest, having come suddenly, he may find you sleeping;

³⁷  and what I say to you, I say to all, Watch.'
