Matthew 24:37-39 (New King James Version)

³⁷ But as the days of Noah were, so also will the coming of the Son of Man be. ³⁸ For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, ³⁹ and did not know until the flood came and took them all away, so also will the coming of the Son of Man be.
