Parallel
Genesis 19:38
Brenton's English Septuagint · Berean Standard Bible
And the younger also bore a son, and called his name Amman, saying, The son of my family. This is the father of the Ammanites to this present day.
The younger daughter also gave birth to a son, and she named him Ben-ammi (note: Ben-ammi means son of my people.). He is the father of the Ammonites of today.
