"so that the people hear when I speak with you": R. Yehudah says: Whence is it derived that the Holy One Blessed be He said to Moses: I will tell you something (viz. (Ibid. 21), and you will return answer to Me (viz. Ibid. 23), and I will acknowledge your answer (viz. Ibid. 24), so that Israel will say: Great is Moses, whom the L–rd acknowledged (viz. Ibid. 9) "and in you, too, will they believe forever").
