Mark 13:35-37

35So you must watch carefully. You do not know when the master of the house will come back. He might arrive in the evening, or in the middle of the night. Or he might arrive early in the morning, or just before the sun rises.

36When he arrives, he may surprise you. He may even find you asleep!

37I am saying this to you. I am also saying this to everyone else. Always be ready!’
