וַיְהִ֖י כְּשָׁמְעָ֣ם אֶת־הַתּוֹרָ֑ה וַיַּבְדִּ֥ילוּ כָל־עֵ֖רֶב מִיִּשְׂרָאֵֽל׃
백성이 이 율법을 듣고 곧 섞인 무리를 이스라엘 가운데서 몰수히 분리케 하였느니라
Ibn Ezra
…God’s community meaning, he shall not be considered as one of God ’s community for purposes of marriage to an Israelite woman [Qiddushin 72b–73a]. The same applies to an Ammonite (but not an Ammonitess), and a Moabite (but not a Moabitess).
