Matthew 24:36-39

But of that day and hour knoweth no one, not even the angels of heaven, neither the Son, but the Father only. And as were the days of Noah, so shall be the coming of the Son of man. For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark, and they knew not until the flood came, and took them all away; so shall be the coming of the Son of man.
