Matthew 24:35-39

35Heaven and earth [as now known] will pass away, but My words will not pass away.

36“But of that [exact] day and hour no one knows, not even the angels of heaven, nor the Son [in His humanity], but the Father alone.

37For the coming of the Son of Man (the Messiah) will be just like the days of Noah.

38For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the [very] day when Noah entered the ark,

39and they did not know or understand until the flood came and swept them all away; so will the coming of the Son of Man be [unexpected judgment].
