הלכה על דברים 23:6

That an Ammonite or a Moabite not enter the Congregation of the Lord: That we should not marry with the males of the Children of Ammon and Moav forever, and even after they convert, as it is stated (Deuteronomy 23:4), "An Ammonite or a Moabite may not come into the Congregation of the Lord forever."
