and [God] said, “Hear these My words: When prophets of ה' arise among you, I make Myself known to them in a vision, I speak with them in a dream.

From among your own people, your God ה' will raise up for you a prophet like myself; that is whom you shall heed.

Never again did there arise in Israel a prophet like Moses—whom ה' singled out, face to face,

It is [one] of the foundations of [our] faith that God conveys prophecy to man.
Prophecy is bestowed only upon a very wise sage of a strong character, who is never overcome by his natural inclinations in any regard. Instead, with his mind, he overcomes his natural inclinations at all times. He must [also] possess a very broad and accurate mental capacity.
A person who is full of all these qualities and is physically sound [is fit for prophecy]. When he enters the Pardes and is drawn into these great and sublime concepts, if he possesses an accurate mental capacity to comprehend and grasp [them], he will become holy. He will advance and separate himself from the masses who proceed in the darkness of the time. He must continue and diligently train himself not to have any thoughts whatsoever about fruitless things or the vanities and intrigues of the times.
Instead, his mind should constantly be directed upward, bound beneath [God's] throne [of Glory, striving] to comprehend the holy and pure forms and gazing at the wisdom of the Holy One, blessed be He, in its entirety, [in its manifold manifestations] from the most elevated [spiritual] form until the navel of the earth, appreciating His greatness from them. [After these preparations,] the divine spirit will immediately rest upon him.
When the spirit rests upon him, his soul becomes intermingled with the angels called ishim, and he will be transformed into a different person and will understand with a knowledge different from what it was previously. He will rise above the level of other wise men, as [the prophet, Samuel] told Saul [I Samuel 10:6]: "[The spirit of God will descend upon you] and you shall prophesy with them. And you will be transformed into a different person."

When a prophet is informed of a message in a vision, it is granted to him in metaphoric imagery. Immediately, the interpretation of the imagery is imprinted upon his heart, and he knows its meaning.
For example, the ladder with the angels ascending and descending envisioned by the patriarch, Jacob, was an allegory for the empires and their subjugation [of his descendants]. Similarly, the creatures Ezekiel saw, the boiling pot and the rod from an almond tree envisioned by Jeremiah, the scroll Ezekiel saw, and the measure seen by Zechariah [were all metaphoric images]. This is also true with regard to the other prophets.
Some would relate the allegory and its explanation as these did. Others would relate only the explanation. At times, they would relate only the imagery without explaining it, as can be seen in some of the prophecies of Ezekiel and Zechariah.
All of the prophecies come in the form of metaphoric imagery and allegories.

All the statements made above describe the path of prophecy of all the early and later prophets, with the exception of Moses, our teacher, the master of all prophets.
What is the difference between Moses' prophecy and that of all the other prophets? [Divine insight is bestowed upon] all the [other] prophets in a dream or vision. Moses, our teacher, would prophesy while standing awake, as [Numbers 7:89] states: "When Moses came into the Tent of Meeting to speak to Him, he heard the Voice speaking to him."
[Divine insight is bestowed upon] all the [other] prophets through the medium of an angel. Therefore, they perceive only metaphoric imagery and allegories. Moses, our teacher, [would prophesy] without the medium of an angel, as [Numbers 12:8] states: "Mouth to mouth I speak to him," and [Numbers 12:8] states: "He gazes upon the image of God" - i.e., there was no metaphor. Rather, he would perceive the matter in its fullness, without metaphor or allegory. The Torah testifies concerning him [Numbers 12:8]: ["I speak to him...] manifestly, without allegory." His appreciation of prophecy would not be through metaphor, but through open revelation, appreciating the matter in its fullness. All the [other] prophets are overawed, terrified, and confounded [by the revelations they experience], but Moses, our teacher, would not [respond in this manner], as [Exodus 33:11] relates: "[God spoke to Moses...] as a man speaks to a friend" - i.e., just as a person will not be awe-struck from hearing his friend's words, so, too, Moses' mental power was sufficient to comprehend the words of prophecy while he was standing in a composed state.
All the [other] prophets cannot prophesy whenever they desire. Moses, our teacher, was different. Whenever he desired, the holy spirit would envelop him, and prophecy would rest upon him. He did not have to concentrate his attention to prepare himself [for prophecy], because his [mind] was always concentrated, prepared, and ready [to appreciate spiritual truth] as the angels [are]. Therefore, he would prophesy at all times, as [Numbers 9:8] states: "Stand and hear what God will command you."
He was promised this by God, as [implied by Deuteronomy 5:27-28]: "Go and tell them: `Return to your tents,' but you stand here together with Me." This should be interpreted to mean: When prophecy departs from all the [other] prophets, they return to their "tents" - i.e., the needs of the body like other people. Therefore, they do not separate themselves from their wives. Moses, our teacher, never returned to his original "tent." Therefore, he separated himself from women and everything of that nature forever. He bound his mind to the Eternal Rock. [Accordingly,] the glory never left him forever. The flesh of his countenance shone, [for] he became holy like the angels.

Thus, those to whom [Moses] was sent witnessed [his appointment] as a prophet, and it was not necessary to perform another wonder for them. He and they were witnesses, like two witnesses who observed the same event together. Each one serves as a witness to his colleague that he is telling the truth, and neither has to bring any other proof to his collegue.
Similarly, all Israel were witnesses to [the appointment of] Moses, our teacher, at the [revelation] at Mount Sinai, and it was unnecessary for him to perform any further wonders for them.
This concept [is alluded to in the interchange between God and Moses at the revelation of the burning bush]. At the beginning of his prophecy, the Holy One, blessed be He, gave him the signs [and wonders] to perform in Egypt and told him [Exodus 3:18], "And they will listen to your voice."
Moses, our teacher, knew that one who believes [in another person] because of signs has apprehension in his heart; he has doubts and suspicions. Therefore, he sought to be released from the mission, saying: "They will not believe me" [Exodus 4:1], until the Holy One, blessed be He, informed him that these wonders [were intended only as a temporary measure,] until they left Egypt. After they would leave, they would stand on this mountain and all doubts which they had about him would be removed.
[God told him:] Here, I will give you a sign so that they will know that I truly sent you from the outset, and thus, no doubts will remain in their hearts. This is what is meant by [Exodus 3:12]: "This will be your sign that I sent you: When you take the people out of Egypt, you will serve God on this mountain."
Thus, we do not believe in any prophet who arises after Moses, our teacher, because of the wonder [he performs] alone, as if to say: If he performs a wonder we will listen to everything he says. Rather, [we believe him] because it is a mitzvah which we were commanded by Moses who said: If he performs a wonder, listen to him.
Just as we are commanded to render a [legal] judgment based on the testimony of two witnesses, even though we do not know if they are testifying truthfully or falsely, similarly, it is a mitzvah to listen to this prophet even though we do not know whether the wonder is true or performed by magic or sorcery.

Therefore, if a prophet arises and attempts to dispute Moses' prophecy by performing great signs and wonders, we should not listen to him. We know with certainty that he performed those signs through magic or sorcery. [This conclusion is reached] because the prophecy of Moses, our teacher, is not dependent on wonders, so that we could compare these wonders, one against the other. Rather we saw and heard with our own eyes and ears as he did.
To what can this be compared? To witnesses who gave testimony concerning a matter to a man who had observed the situation with his own eyes. He will never listen to them and will know for certain that they are false witnesses.
Therefore, the Torah states (Deuteronomy 13:3-4) that "[Even] if [such] a sign or wonder will come, you should not listen to the words of that prophet." He comes to you with signs and wonders to deny what you saw with your own eyes. We believe in a wonder [as evidence of a prophet's reliability] only because of the mitzvah which Moses commanded us. Therefore, how can a wonder [cause us to] accept this [person] who comes to deny the prophecy of Moses which we saw and heard?
