Genesis 19:36-38 ▼

36 Thus the two daughters of Lot became pregnant by their father.

37 The firstborn gave birth to a son whom she named Moab, saying, “From my father.” He is the ancestor of the Moabites of today.

38 The younger one, too, gave birth to a son, and she named him Ammon, saying, “The son of my kin.” He is the ancestor of the Ammonites of today.
