Devarim Rabbah

“These are the words that Moses spoke to all Israel beyond the Jordan; in the wilderness, in the Arava, opposite the Red Sea, between Paran and Tofel, and Laban, and Hatzerot, and Di Zahav” (Deuteronomy 1:1). “These are the words” – halakha: Is it permissible for a person of Israel to write a Torah scroll in any language? This is what the sages taught: The difference between Torah scrolls and phylacteries and mezuzot is only that Torah scrolls may be written in any language. Rabban Gamliel says: Even Torah scrolls, the Sages permitted to be written only in Greek. What is the source for Rabban Gamliel who says that it is permitted to write a Torah scroll in Greek? This is what our Rabbis learned: Bar Kappara said: It is written: “May God expand Yefet, and may he dwell in the tents of Shem” (Genesis 9:27) – let the words of Shem be stated in the language of Yefet. That is why they permitted them to write it in Greek. The Holy One blessed be He said: ‘See the language of the Torah, how dear it is, that it cures the tongue.’ From where is it derived? As it is written: “A healing tongue is a tree of life” (Proverbs 15:4), and a tree of life is nothing but Torah, as it is stated: “It is a tree of life for those who grasp it” (Proverbs 3:18). The language of the Torah unencumbers the tongue. Know that in the future, the Holy One blessed be He will take up excellent trees from the Garden of Eden. What is their excellence? It is that they cure the tongue, as it is stated: “Along the stream, upon its bank, on this side and on that side, [will grow every food tree]” (Ezekiel 47:12). From where is it derived that it is a cure for the tongue? As it is stated: “Its fruit will be for food and its leaf for healing” (Ezekiel 47:12). Rabbi Yoḥanan and Rabbi Yehoshua ben Levi, one said: ‘It is a medicine,’ and one said: ‘Anyone who is mute and tastes of it, his tongue will be cured and it will immediately articulate matters of Torah,’ as so it is written: “on this side and on that side,” and [the phrase] “on this side and on that side” is [a reference to] nothing other than Torah, as it is stated: “[Tablets that were inscribed on both sides,] from this side and from that side they were inscribed” (Exodus 32:15). Rabbi Levi said: Why should we learn from elsewhere? Let us learn from its own place, as Moses, before he was privileged to receive the Torah, it is written in his regard: “I am not a man of words” (Exodus 4:10). When he was privileged to receive the Torah, his tongue was cured and he began speaking words. From where is it derived? From what we read in this context: “These are the words that Moses spoke.”
