BBE(i)
33 Take care, keep watch with prayer: for you are not certain when the time will be.
34 It is as when a man who is in another country for a time, having gone away from his house, and given authority to his servants and to everyone his work, gives the porter an order to keep watch.
35 So you are to keep watch: because you are not certain when the master of the house is coming, in the evening, or in the middle of the night, or at the cock's cry, or in the morning;
36 For fear that, coming suddenly, he sees you sleeping.
37 And what I say to you, I say to all, Keep watch.
