Reference for Sanhedrin 117:3
וליחשבה גבי שבע מצות מ"ד מורשה מיגזל קא גזיל לה מאן דאמר מאורסה דינו כנערה המאורסה דבסקילה
<font>it is <i>our</i> inheritance, not theirs</font>.<span class="x" onmousemove="('comment',' This seems a very strong expression. In the J. E. (loc. cit.) it is suggested that R. Johanan feared the knowledge of Gentiles in matters of Jurisprudence, as they would use it against the Jews in their opponents' courts. In support of this it may be observed that the Talmud places R. Johanan's dictum (which, of course, is not to be taken literally) immediately after the passage dealing with the setting up of law courts by Gentiles. It is also possible that R. Johanan's objection was to the studying of Oral Law by Jewish Christians, as the possession of the Oral Law was held to be the distinguishing mark of the Jews. It is significant that it was R. Johanan who also said that God's covenant with Israel was only for the sake of the Oral Law. (Cf. Ex. Rab. 47.) ');"><sup>3</sup></span>
