3 Have in mind therefore in what manner thou hast received and heard: and observe and do penance: If then thou shalt not watch, I will come to thee as a thief: and thou shalt not know at what hour I will come to thee.
3
Remember, therefore, what you have received and heard; hold it fast, and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.
