Mark 13:34-35
13:34 It is like a man going on a journey. He left his house and put his slaves in charge, assigning to each his work, and commanded the doorkeeper to stay alert.
13:35 Stay alert, then, because you do not know when the owner of the house will return – whether during evening, at midnight, when the rooster crows, or at dawn –
Mark 13:37
13:37 What I say to you I say to everyone: Stay alert!”
