-All Languages stem from seventy arch Languages. As time went they changed, split and evolved as they manifest the concepts they represent.
-The members of the Sanhedrin (The high court of Yisroel) had to be fluent in all seventy languages.
-The simple reason for this is they had to be prepared to accept testimony from any witness who came before the court.

-All the Wisdom in the World is contained in the Hebrew language. The words themselves are manifestations of the same concept that they represent. The Kabbalists know how to permeate the words to learn the greatest mysteries from them. Many Kabbalah Books (Sefarim) are composed totally of such Torah.
- The Seventy Languages stem from Hebrew. Rabbi Avraham Abulafia thought that they come from the "Backside" of Hebrew.
-Most of the world's wisdom can be found in the Hebrew Language but to see how it manifest in the Sitra Acher one has to know all seventy Languages.
-The Sanhedrin was composed of the biggest Kabbalists and they had to be complete in Wisdom.
-This also explains why some Kabbalists bring proof to their words from other languages.
