Mark 13:37

And what I say unto you I say unto all, 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:

Take ye heed, watch and pray: for ye know not when the time is.

Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all?
