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

Then you watch, for you do not know when the lord of the house is coming, at evening, or at midnight, or at cockcrowing, or early;

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

And Peter said to Him, Lord, do You speak this parable to us or also to all?
