Genesis 19:36-38 ASV
Thus were both the daughters of Lot with child by their father. And the first-born bare a son, and called his name Moab: the same is the father of the Moabites unto this day. And the younger, she also bare a son, and called his name Ben-ammi: the same is the father of the children of Ammon unto this day.
