Now that Scripture has included and excluded, you must revert to the first line of reasoning, viz.: If "mamzer," whereof it is not stated "for all time," women are equated with men, then Amonim and Moavim, whereof it is stated "for all time," how much more so should men be equated with women! It is, therefore, written "Amoni," and not "Amonith." These are the words of R. Yehudah. R. Shimon says (Ibid. 23:5) "Because they did not greet you with bread and with water." Whose custom is it to greet? Men and not women, (women normally being in the home.)
