Genesis 19:38 YLT

³⁶  And the two daughters of Lot conceive from their father,

³⁷  and the first-born beareth a son, and calleth his name Moab; he 'is' father of Moab unto this day;

³⁸  as to the younger, she also hath born a son, and calleth his name Ben-Ammi: he 'is' father of the Beni-Ammon unto this day.
