Midrash for Exodus 19:13

R. Nachman b. R. Chisda said to R. Nachman b. Isaac: "Let the master come and settle among us [so that we may study together]." We are taught in a Mishnah, answered the latter, "Not the place in which he lives distinguishes the man, but the man marks the place. And thus we find that with respect to Mount Sinai, as long as the Shechina rested there, the Torah admonishes (Ex. 34, 3) Neither let flocks or herds feed near the mount, but as soon the Shechina had withdrawn from the mount, it is said (Ex. 19, 13) They may come up to the mount. A similar instance can be found with respect to the Tabernacle, which was erected in the wilderness, that so long as the Tabernacle was pitched the Torah warned (Num. 5, 2)They send out of the camp every leper, etc. When the curtains [of the Tabernacle] were folded up immediately the lepers and Zab were allowed to enter the place." "If this be so," said R. Nachman b. R. Chisda "then I will go to the place where the master dwellest." Whereupon R. Nachman b. Isaac answered: "It is better that a Maneh son of a P'ras (half a Maneh), i.e., a distinguished son of a less distinguished father — should come to be a Maneh son of a Maneh, i.e., a distinguished son of a distinguished father, rather than the contrary."

10) (Vayikra 24:23) ("And Moses spoke to the children of Israel, and they took the curser outside the camp, and they stoned him with a stone; and the children of Israel did as the L–rd commanded Moses.") "And Moses spoke to the children of Israel, and they took the curser outside the camp. As mentioned earlier (Chapter 19:1), we are hereby taught that beth-din was within, and beth-din, outside of it. "and they stoned him," and not his garment (viz. Chapter 19:3). "a stone": We are hereby taught that if he died with one stone, it is sufficient. "and the children of Israel did as the L–rd commanded Moses": both in respect to semichah (placing of the hands, viz. Vayikra 24:14), in respect to dechiyah (casting him from the stoning platform, viz. Shemoth 19:13), in respect to hanging (his body on a tree) (viz. Devarim 21:22), and in respect to (Devarim 21:23) "His corpse shall not remain on the tree."

Another matter, “there as a small city” – this is Sinai, “and few men in it” – these are the Israelites, “and a great king came against it” – this is the King of kings the Holy One blessed be He, “and surrounded it and built a great siege upon it” – these are the two hundred and forty-eight positive commandments and the three hundred and sixty-five negative commandments. “He found in it a poor, wise man” – this is Moses, as it is stated: “No hand shall touch it…” (Exodus 19:13), “and he saved the city in his wisdom” – as it is stated: “Anyone who touches the mountain shall be put to death” (Exodus 19:12). “But no one remembered…” – the Holy One blessed be He said: You did not remember him; I remember him, as it is stated: “Remember the Torah of Moses, My servant…” (Malachi 3:22).
