Let your waists be girded about, and your lamps burning; And you yourselves be like unto men that wait for their lord, when he will return from the wedding; that when he comes and knocks, they may open unto him immediately. Blessed are those servants, whom the lord when he comes shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to eat, and will come forth and serve them. And if he shall come in the second watch, or come in the third watch, and find them so, blessed are those servants. And this know, that if the owner of the house had known what hour the thief would come, he would have watched, and not have allowed his house to be broken through. Be you therefore ready also: for the Son of man comes at an hour when you think not. (Luke 12:35-40)
