Mark 13:33
King James Version
“Take ye heed, watch and pray: for ye know not when the time is.”
Context
30Verily I say unto you, that this generation shall not pass, till all these things be done.
31Heaven and earth shall pass away: but my words shall not pass away.
32But of that day and hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
33Take ye heed, watch and pray: for ye know not when the time is.
34as 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.
35Watch 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:
36Lest coming suddenly he find you sleeping.
