Genesis 19:36-38

36Thus both the daughters of Lot became pregnant by their father. 37The firstborn bore a son and called his name Moab.
 Moab sounds like the Hebrew for from father
bHe is the father of the Moabites to this day.
38The younger also bore a son and called his name Ben-ammi.
 Ben-ammi means son of my people
dHe is the father of the Ammonites to this day.
