R. Elazar Hamodai says: He sent him with all the honor in the world, as is seen in his (Moses') response to him, as it is written (Numbers 10:30) "I pray you, do not leave us," telling him: You gave us good and beautiful counsel, and the L–rd consented to your words. "I pray you, do not leave us." Yithro replied: Is a candle of benefit other than in a place of darkness? Can sun and moon benefit from a candle? You are the sun and Aaron your brother is the moon. What can a candle do between you? Let me go to my land and I will convert all of my countrymen and bring them to the study of Torah and under the wings of the Shechinah.
