이사야 40:5 미드라쉬: Vayikra Rabbah, Mekhilta DeRabbi Yishmael, Midrash Tehillim & Aggadat Bereshit

What is the difference between Moses and all the [other] prophets? Rabbi Yehuda ben Rabbi Ilai and the Rabbis: Rabbi Yehuda says: The prophets would see through nine looking glasses. That is what is written: “The appearance of the vision that I saw [was like the vision that I saw when I came to destroy the city; and the visions were like the vision that I saw by the Kevar River]” (Ezekiel 43:3).²²The words appearance, vision, and saw appear a total of eight times, and in one of those instances the word visions appears in plural, for a total of nine. This alludes to the fact that the prophet saw his prophecy as though looking through nine layers of glass. Moses saw through one looking glass, as it is stated: “And a vision and not in riddles” (Numbers 12:8). The Rabbis said: All the prophets saw through a murky looking glass. That is what is written: “[I spoke to the prophets;] I proliferated visions and granted imagery to the prophets” (Hosea 12:11). Moses saw through a polished looking glass. That is what is written: “And a vision and not in riddles” (Numbers 12:8). Rabbi Pinḥas said in the name of Rabbi Hoshaya: This is analogous to a king who revealed himself to a member of his household in his image.²³He allowed him to see the king without any intervening curtains. In this world, the Divine Presence appears only to individuals, but in the future: “The glory of the Lord will be revealed, and all flesh will see together that the mouth of the Lord has spoken” (Isaiah 40:5).

Similarly, (Isaiah 40:5) "The glory of the L–rd shall appear, and all flesh will behold as one, for the mouth of the L–rd has spoken." And where did He speak it? (Devarim 32:39) "See, now, that I — I am He, and there is no god beside Me."

Another thing I swear by righteousness. See the power of charity that a person gives to the poor, he merits and receives the face of the Divine Presence. It can be compared to a carriage driver who wishes to see the king's face. He makes a crown according to his glory, and by placing the crown on the king's head, he sees the king's face. See how powerful charity is that through charity, one receives the face of the Divine Presence, as it is said, "In righteousness I will behold Your face" (Psalms 17:15). What did David see to explain the merit of charity alone? To teach you that even wicked people who have only the merit of charity alone, merit and receive the face of the Divine Presence, as it is said, "And the glory of the Lord will be revealed, and all flesh together shall see" (Isaiah 40:5). Everyone sees, the righteous and the wicked. So what distinguishes the righteous from the wicked? That the wicked know before whom they are sinning, and the righteous know before whom they will stand in judgment.
