Mark 13:37

And what I say unto you I say unto all, Watch.

Watch you therefore: for you know not when the Master of the house comes, at evening, or at midnight, or at the cock crowing, or in the morning:

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

Then Peter said unto him, Lord, speak you this parable unto us, or even to all?
