Mark 13:34-37

34 It is like a man going on a journey who left his house, put each servant in charge of his own task, and instructed the doorkeeper to keep watch.

35 Therefore keep watch, because you do not know when the master of the house will return—whether in the evening, at midnight, when the rooster crows, or in the morning.

36 Otherwise, he may arrive without notice and find you sleeping.

37 And what I say to you, I say to everyone: Keep watch!”
