I have never received a satisfactory answer to the following

question:<br>

We are taught that the Ovos amongst others observed Torah.<br>

Obviously the sheva mitzvos b'nei Noach they observed but how did<br>

they know about the chukim and korbonos, as well as tzitzis,

mezuzah,<br>

tefillin, etc. etc. etc.?</blockquote><br>

Not all the major rishonim actually held that way (i.e., many held that

the Avos did not follow the same halacha as Rashi.<br><br>

Some even criticize that approach:<br><br>

</a>Here's a 110 minute shiur on it (I have not yet heard it), which

starts off by saying that pretty much only Rashi (of the rishonim) held

that<br><br>

</a>I see R Gil Student wrote, in 2004:<br><br>

<blockquote type=cite class=cite cite=""><pre>The Gemara (Yoma 28b) says

that Avraham even kept eiruvei tavshilin, a clear rabbinic commandment

(cf. Rashi). Some, however, translate that as being the equivalent of

ta'aroves tavshilin (mixtures of food) and explain it to mean the

biblical prohibition against cooking meat and milk together, which is

prohibited through the Oral Torah (as stated subsequently in the Gemara).

I believe this explanation is from the Chasam

Sofer.</pre><font face="Courier New, Courier"></font></blockquote></body>
