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. 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." 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. But Moses quieted them, and instantly set about imparting to the people the Torah he had received from God.
