Luke 12:40

Watch therefore: for ye know not what hour your Lord doth come.

Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.

Take ye heed, watch and pray: for ye know not when the time is. For the Son of Man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch. Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: Lest coming suddenly he find you sleeping.

And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares. For as a snare shall it come on all them that dwell on the face of the whole earth. Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.

And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.

Therefore let us not sleep, as do others; but let us watch and be sober.
