33Watch, keep alert, and pray; for you don`t know when the time is. 34"It is like a man, traveling to another country, having left his house, and given authority to his servants, and to each one his work, and also commanded the doorkeeper to keep watch. 35Watch therefore, for you don`t know when the lord of the house is coming, whether at evening, or at midnight, or when the rooster crows, or in the morning; 36lest coming suddenly he might find you sleeping. 37What I tell you, I tell all: Watch."
Mark 13:32-37 (WEB)
