Matthew 24:36 King James Version
36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.

And a few lines down:
Matthew 24:38-39
For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.
