Matthew 24:35-39

35Heaven and earth will pass away, but my words will never pass away.

36“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.

37As it was in the days of Noah, so it will be at the coming of the Son of Man.

38For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark;

39and 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.
