"Be on guard, keep awake. For you do not know when the time will come. It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to stay awake. Therefore, stay awake — for you do not know when the master of the house will come, in the evening, or at midnight, or when the rooster crows, or in the morning — lest he come suddenly and find you asleep. And what I say to you I say to all: Stay awake."
