"The third month was chosen for the revelation, because everything that is closely connected with the Torah and with Israel is triple in number. The Torah consists of three parts, the Pentateuch, the Prophets, and the Hagiographa; similarly the oral law consists of Midrash, Halakah, and Haggadah. The communications between God and Israel were carried on by three, Moses, Aaron, and Miriam. Israel also is divided into three divisions, priests, Levites, and laymen; and they are, furthermore, the descendants of the three Patriarchs, Abraham, Isaac, and Jacob. For God has a preference for "the third": It was the third of Adam's sons, Seth, who became the ancestor of humanity, and so too it was the third among Noah's sons, Shem, who attained high station. Among the Jewish kings, too, it was the third, Solomon, whom God distinguished before all others. The number three plays a particularly important part in the life of Moses. He belonged to the tribe of Levi, which is not only the third of the tribes, but has a name consisting of three letters. He himself was the third of the children of the family; his own name consists of three letters; in his infancy he had been concealed by his mother throughout three months; and in the third month of the year, after a preparation of three days, did he receive the Torah on a mountain, the name of which consists of three letters."
