Mark 13:33–37
33 Take heed, watch and pray;a for you do not know when the time will come. 34 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 be on the watch. 35 Watch therefore—for you do not know when the master of the house will come, in the evening, or at midnight, or at cockcrow, or in the morning— 36 lest he come suddenly and find you asleep. 37 And what I say to you I say to all: Watch.”
