The book of Deuteronomy opens, “These are the words which Moses spoke to all Israel across the Jordan in the wilderness, in the Arabah” (Deuteronomy 1:1). Those words preface more than thirty chapters of Moses continuously talking. The sages puzzled over this. How did the man who was slow of speech become so eloquent? Just a few verses later, it says, “Moses undertook to expound this Torah.” According to Jewish tradition, Moses expounded the Torah in the seventy languages. The Midrash Tanchuma takes up the discussion.
Come and see! When the Holy One, blessed be He, said to Moses, “Go and I will send you to Pharaoh,” Moses said, “Woe! You are giving over the mission to me? I am not a man of words.” He said, “There are seventy languages known in Pharaoh’s court, so that if anyone comes from a foreign country, they can speak to him in his language. I am going as your apostle, and they will question me, and I will tell them that I am an apostle of the Almighty, and it will be obvious to them that I do not know how to converse with them. Will they not mock me and say, ‘Look, the apostle of the Creator of the universe who created all the tongues! He is unable to comprehend or answer.’” This is what Moses meant when he said, “Woe, I am not a man of words.” … forty years after the exodus from Egypt, however, he expounded the Torah in seventy languages, as it says, “He explained this Torah.” (Midrash Tanchuma, Devarim 2)
According to this story, Moses felt unqualified to serve as an apostle of Hashem because he could not speak in all seventy languages. After the giving of the Torah at Mount Sinai (i.e., Shavuot) Moses no longer suffered with that impediment. He demonstrated to the people of Israel that he could now teach Torah in all seventy languages.
We should be able to see the connection to our apostles who spoke the good news in all languages on the day of Shavuot. On that day that they became apostles of the Almighty and His risen Son, they received the gift of languages.
The seventy tongues represent the seventy mother-languages spoken by all humanity. The presentation of the Torah in every language alludes to the universal quality of the revelation of God through the Torah of Moses. Just as Moses is said to have expounded the Torah to Israel in every language, likewise, the disciples proclaimed the good news of Yeshua on Shavuot in every language.
Expounding the Torah is a job for every disciple. In the same way that it is incumbent upon us to spread the gospel in every place and at every time, it is also incumbent upon us to teach the Torah. After all the Torah is very much a part of the gospel, and the message of the gospel is quite meaningless without the Torah. Therefore, we are all called to emulate Yeshua, our teacher, who dedicated His life to proclaiming the gospel and teaching the ways of Torah.
When properly presented, the Torah should be an avenue to Messiah. It should be a central part of the good news of the kingdom and the call for repentance in the name of our Master. One who undertakes to teach the Torah to others is like one imbued with the Holy Spirit on the day of Shavuot.
