Mark 13:34-37

34“The coming of the Son of Man can be illustrated by the story of a man going on a long trip. When he left home, he gave each of his slaves instructions about the work they were to do, and he told the gatekeeper to watch for his return.

35You, too, must keep watch! For you don’t know when the master of the household will return—in the evening, at midnight, before dawn, or at daybreak.

36Don’t let him find you sleeping when he arrives without warning.

37I say to you what I say to everyone: Watch for him!”
