Mark 13:33-37American Standard Version (ASV)
33 Take ye heed, watch [a]and pray: for ye know not when the time is. 34 It is as when a man, sojourning in another country, having left his house, and given authority to his [b]servants, to each one his work, commanded also the porter to watch. 35 Watch 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; 36 lest coming suddenly he find you sleeping. 37 And what I say unto you I say unto all, Watch.
