R. Shimon said (to them:) What I am saying follows a fortiori, viz. If where Scripture forbade the males (from entry) forever (i.e., in the instance of Amon and Moav), it permitted the daughters immediately, then, where it forbade the males only until three generations (i.e., in the instance of an Edomi), how much more so should the females be permitted immediately! They responded: If you are stating a halachah, we will accept it; if you are ratiocinating, we can answer you. R. Shimon: I am stating a halachah, and the verse supports me — "banim" (sons), and not "banoth" (daughters).
