Matthew 24:37-39 New American Standard Bible (NASB)
37 For [a]the coming of the Son of Man will be just like the days of Noah. 38 For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, 39 and they did not [b]understand until the flood came and took them all away; so will the coming of the Son of Man be.
Matthew 24:37-39 Young's Literal Translation (YLT)
37 and as the days of Noah -- so shall be also the presence of the Son of Man;
38 for as they were, in the days before the flood, eating, and drinking, marrying, and giving in marriage, till the day Noah entered into the ark,
39 and they did not know till the flood came and took all away; so shall be also the presence of the Son of Man.
