"But of that day or that hour no one knows, not even the angels in heaven, nor the Son, but only the Father.
Take heed, watch; for you do not know when the time will come.
It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to be on the watch.
Watch therefore--for you do not know when the master of the house will come, in the evening, or at midnight, or at cockcrow, or in the morning--
lest he come suddenly and find you asleep.
And what I say to you I say to all: Watch."
