When Moses had complete the writing of the Torah, he wiped his pen on the hair of his forehead, and from this heavenly ink that cleaved to his forehead originated the beams of light that radiated from it. [309] In this way God fulfilled to Moses the promise: "Before all thy people I will do marvels, such as have not been done in all the earth, nor in any nation." [310] On Moses' return from heaven, the people were greatly amazed to see his face shining, and there was fear, too, in their amazement. This fear was a consequence of their sin, for formerly they had been able to bear without fear the sight of "the glory of the Lord that was like devouring fire," although it consisted of seven sheaths of fire, laid one over another; but after their transgression they could not even bear to look upon the countenance of the man who had been the intermediator between themselves and God. [311] But Moses quieted them, and instantly set about imparting to the people the Torah he had received from God. His method of instruction was as follows: first came Aaron, to whom he imparted the word of God, and as soon as he had finished with Aaron, came the sons of Aaron, Eleazar and Ithamar, and he instructed them, while Aaron sat at his right hand, listening. When he had finished with the sons of Aaron, the elders appeared to receive instruction, while Eleazar sat at the right hand of his father, and Ithamar at the left hand of Moses, and listened; and when he had finished with the elders, the people came and received instruction, whereupon Moses withdrew. Then Aaron went over what had been taught, and his sons likewise, and the elders, until every one, from Aaron down to every man out of the people, had four times repeated what he had learned, for in this way had God bidden Moses impress the Torah four times upon Israel.
