25 And the Lord God said: 'Open his mouth and his ears, that he may hear and speak with his mouth, with the language which has been revealed'; for it had ceased from the mouths of all the children of men from the day of the overthrow (of Babel). 26 And I opened his mouth, and his ears and his lips, and I began to speak with him in Hebrew in the tongue of the creation. 27 And he took the books of his fathers, and these were written in Hebrew, and he transcribed them, and he began from henceforth to study them, and I made known to him that which he could not (understand), and he studied them during the six rainy months.
Genesis Rabbah 18:4Aggadah
Resh Lakish was asked: Why do not all other dreams exhaust a man, yet this [a dream that intimacy takes place] does exhaust a man? Because from the very beginning of her creation she was but [formed] in a dream, replied he. BONE OF MY BONES, AND FLESH OF MY FLESH. R. Tanhuma said: When a man takes one of his relations to wife, of him it is said, BONE OF MY BONES, AND FLESH OF MY FLESH. SHE SHALL BE CALLED, WOMAN (ISHAH), BECAUSE SHE WAS TAKEN OUT OF MAN (ISH). From this you learn that the Torah was given in the Holy Tongue.’ R. Phinehas and R. Helkiah in R. Simon’s name said: Just as it was given in the Holy Tongue, so was the world created with the Holy Tongue. Have you ever heard one say, gini, ginia; itha, ittha; antropt, antropia; gabra, gabretha?* But ish and ishah [are used]: why? because one form corresponds to the other.
Notes and References
"... Jubilees portrays animals as even more rational than in the Bible. Language is important to Jubilees and is original to creation. Thus, it seems that even animals spoke Hebrew in the beginning. (Vander Kam sees this possibility as well, referencing Jubilees 12:26 about Hebrew as the language of creation. Ruiten notes that “it was universally believed among Jews that Hebrew was the primitive language of man ... God also spoke Hebrew when creating the world”. See also Jerusalem Talmud, Megillah 1:11; Targum Pseudo-Jonathan Genesis 11:1 ... “and all the inhabitants of the earth were of one tongue and one speech and one counsel”) Targum Neofiti (Genesis 11:1) may also hint that animals could speak with humans and each other: “and all the inhabitants of the earth were of one tongue and one speech, and in the language of the Temple they used to converse, for through it had the world been created in the beginning.” ..."
