And Moses saw in the seventh heaven the holy Hayyot, which support the throne of God; and he beheld also the angel Zagzagel, the prince of the Torah and of wisdom, who teaches the Torah in seventy languages to the souls of men, and thereafter they cherish the precepts contained therein as laws revealed by God to Moses on Sinai. From this angel with the horns of glory Moses himself learnt all the ten mysteries."
Having seen what there is in the seven heavens, he spoke to God, saying, "I will not leave the heavens unless Thou grantest me a gift," and God replied, "I will give thee the Torah, and men shall call it the Law of Moses."
