Mark 13:33–37
33Stay alert, keep watch, and pray, because you don't know when the time will come. 34It's like a man who goes on a long journey. Before leaving, he puts his servants in charge, assigns each one a task, and tells the doorkeeper to stay alert. 35So stay watchful, because you don't know when the master of the house will return — whether in the evening, at midnight, at the rooster's crow, or at dawn. 36Don't let him arrive suddenly and find you asleep. 37What I'm telling you, I'm telling everyone: Stay watchful!"
