Halakha Bilangan 9:8: Mishneh Torah, Foundations

All the things hereinof spoken is the path of prophecy for all prophets, First and Last, save Moses our Master, the Master of all prophets. And what division is there between the prophecy of Moses and that of all the other prophets? All the other prophets prophesied while in a dream, or in a vision, but Moses our Master prophesied while awake and standing up, as it is said: "And when Moses went into the tent of meeting that He might speak with Him, then he heard the Voice speaking unto him" (Num. 7.89); all other prophets received it through an Angel, they therefore saw what they did see in the form of allegory and riddles, but Moses our Master did not receive it through an angel, for it is said: "With him do I speak mouth to mouth" (Ibid. 12.8), and it is also said: "and the Lord spoke unto Moses face to face" (Ex. 33.11); and it is further said: "And the similitude of the Lord doth he behold" (Num. 12.8); which is to say that there is no manner of parable, for he sees the matter in its clearness without riddle and without parable, which is as the Torah testifies concerning him: "Even manifestly, and not in dark speeches" (Ibid.); he does not prophesy in dark speech but by sight for he sees the matter in its clearness; all prophets are awe-stricken, trembling and faint, but Moses our Master is not so, which is as the Verse says: "As a man speaketh unto his friend" (Ex. 33.11), meaning, that as no man trembles to hear the words of his friend, so was the power of the mind of Moses our Master to understand the words of prophecy, he remaining upright at his post unaffected; all other prophets could not prophesy any time they wanted, but not so Moses our Master, who at any time he desired, the Holy Spirit covered him, and prophecy rested upon him, and he needed not to prepare his mind, or be in readiness to meet it, as he was prepared and ready constantly like unto the ministering Angels. He, therefore, prophesied at all times, even as it is said: "Stand ye and let me hear what God will command concerning you" (Num. 9.8). Moreover, in this, Almighty assured him, saying: "Go and say to them, 'Return ye to your tents' and, as for thee, remain standing with me here"(Deut. 5.30–31). Herefrom we learn that all other prophets, when the spirit of prophecy departs from them, return to their tent for their bodily needs, they all, like unto the rest of the people. Therefore, do they not remain separated from their wives. But Moses our Master returned not again to his erstwhile abode, he therefore separated himself forever from his wife and from like matters; his intellect became apprenticed to the Rock of the Universe; glory never departed from him; his countenance became adorned with rays of light, and his saintliness was like that of Angels.
