Matthew 24:40 WEB

³⁸  For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ark,

³⁹  and they didn't know until the flood came, and took them all away, so will be the coming of the Son of Man.

⁴⁰  Then two men will be in the field: one will be taken and one will be left;

⁴¹  two women grinding at the mill, one will be taken and one will be left.

⁴²  Watch therefore, for you don't know in what hour your Lord comes.
