Mark 13:37

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

Watch ye therefore, for ye know not when the Lord of the house comes: at evening or at midnight or at the cockcrowing or in the morning,

Take ye heed, watch and pray; for ye know not when the time shall be.

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