Mark 13:32–37

But of that day or hour no man knoweth, neither the angels in heaven, nor the Son, but the Father. 33Take ye heed, watch and pray. For ye know not when the time is. 34Even as a man who, going into a far country, left his house and gave authority to his servants over every work and commanded the porter to watch. 35Watch ye therefore (for you know not when the lord of the house cometh, at even, or at midnight, or at the cock crowing, or in the morning): 36Lest coming on a sudden, he find you sleeping. 37And what I say to you, I say to all: Watch.
