In a recent Torah reading, it talked about the daughters of Zelophehad choosing to marry within their tribe, in order to keep their father's inheritance within his tribe.
The guest rabbi, whom I heard recently, mentioned something to the effect that that particular Torah command, of the women commanded to marry within their tribe, was only a mitzvah "for that generation and not to be repeated from generation to generation".
My question, which are directed to those who know the Gemara, Mishna, Halacha, etc., is:
What other Torah commands are there, if any, that were only meant "for that generation and not to be repeated from generation to generation"?
