Genesis 19:36-38 New Life Version (NLV)
36 So both the daughters of Lot were going to have a child by their father. 37 The first-born daughter gave birth to a son, and gave him the name Moab. He is the father of the Moabites to this day. 38 The younger daughter gave birth to a son also. She gave him the name Benammi. He is the father of the Ammonites to this day.
