Mark 13:34-37

Riverside(i) 34 It is just as when a man going abroad leaves his house and gives to his servants authority and to each his work and commands the porter to watch. 35 Watch, therefore, for you do not know when the Master of the house will come, whether at evening or at midnight or at cock-crowing or in the morning. 36 Otherwise coming suddenly he may find you sleeping. 37 What I say to you, I say to all, Watch."
