Mark 13:37

Watch: I say it to you, and I say it to all."

Watch then, for you never know when the Lord of the House will come, in the late evening or at midnight or at cock-crow or in the morning.

Take care, keep awake and pray; you never know the time.

Peter said, "Lord, are you telling this parable for us, or is it for all and sundry?"

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

Keep on the watch then, for you know neither the day nor the hour.

Take care, keep awake and pray; you never know the time.
