וַתֵּ֤לֶד הַבְּכִירָה֙ בֵּ֔ן וַתִּקְרָ֥א שְׁמ֖וֹ מוֹאָ֑ב ה֥וּא אֲבִֽי־מוֹאָ֖ב עַד־הַיּֽוֹם׃
A primogênita deu a luz a um filho, e chamou-lhe Moabe; este é o pai dos moabitas de hoje.
Targum Jonathan on Genesis
And the elder brought forth a son, and she called his name Moab, because from her father she had conceived. He is the father of the Moabaee unto this day.
