7. Rabbi Chiya said: One day I was traveling to Rabbi Shimon to be taught by him the laws of the Pesach (Passover). I encountered a mountain and I saw clefts and cavities in one rock, and two men were in there. As I approached, I heard the voices of these people who were saying, "A song, a psalm for the sons of Korah, Great is Hashem and highly to be praised..." (Tehilim 48:1-2). Why "A song, a psalm?" HE ANSWERS: Thus do we learn on behalf of Rabbi Shimon: The song is two-fold, NAMELY A SONG AND A PSALM, and since it is a better song than other songs, it is named "song" twice. Similarly, "A psalm, a poem for the Shabbat day" (Tehilim 92:1), MEANING THAT IT IS MORE PRAISEWORTHY THAN OTHER SONGS. In the same fashion, "the song of songs which is Solomon's" (Shir Hashirim 1:1), INDICATING a song that stands above all other songs.
297. Rabbi Shimon opened the discussion saying, "This is the ordinance of the Pesach: no stranger shall eat of it" (Shemot 12:43). It is also written, "But every man's servant..." (Ibid. 44) and "a foreign and a hired servant shall not eat of it" (Ibid. 45). If something like eating the pascal lamb is forbidden to the uncircumcised just because it hints at a holy matter - MEANING BECAUSE "HASHEM WILL PASS OVER THE DOOR..." (IBID. 23) - then how much more should the Torah, which is the Holy of Holies, the sublime name of the Holy One, blessed be He, be forbidden to them.
