Midrash su Isaia 42:21

(Numb. 8:2:) “When you set up the lamps.” This text is related (to Is. 42:21), “The Lord was delighted because of His [servant's] righteousness to magnify and glorify Torah.” The Holy One, blessed be He, said to Moses, It was not because I need your light that I am telling you to light a lamp.³Below Numb. 3:5; Numb. R. 15:2. Rather [I am doing so] in order to have you acquire merit (by fulfilling a commandment).” It is likewise written, (in Dan. 2:22), “and the light dwells within Him”; and [similarly] it says (in Ps. 139:12), “Even darkness is not dark to You; for night shines as the day, and darkness becomes like the light.” [Scripture says these things] to inform you that He does not need the lamps of flesh and blood. You yourself know [this truth]. When a person builds a house and makes windows within [his house], he makes windows narrow on the outside and broad on the inside, so that the light will enter from the outside and shine on the inside. But when Solomon built the Temple, he did not make the windows like that.⁴See above Exod. 8:5; PRK 21:5; Lev. R. 31:7. Rather they were narrow on the inside and broad on the outside so that the light would go out from the Temple and shine outside. It is so stated (in I Kings 6:4), “And for the house he made windows broad and narrow.”⁵Literally: CLEAR and CLOSED. While the Hebrew is obscure the translation here follows the Targum in order to fit the midrashic context. [This text] is to inform you that He is all light and that He has no need for its light. So why did He command you [to set up the lamps]? In order to have you acquire merit (by fulfilling a commandment). It is therefore stated (in Numb. 8:2), “When you set up the lamps.”⁶Beha‘aloteka et-hanerot. These words can also mean, IN ELEVATING YOU WITH THE LAMPS. Ergo (in Is. 42:21), “The Lord was delighted because of His [servant's] righteousness.” The Holy One, blessed be He, said to Israel, “Be careful to light lamps for My sake, and I will shine a great light for you in the future to come.” It is so stated (in Is. 60:3), “And nations shall walk by your light, even kings by the brightness of your rising.”

Another interpretation (of Numb. 8:2): [WHEN YOU SET UP THE LAMPS.] This text is related (to Is. 42:21): THE LORD WAS DELIGHTED BECAUSE OF HIS <SERVANT'S> RIGHTEOUSNESS TO MAGNIFY AND GLORIFY TORAH. The Holy One, as it were, said to Moses: Say to Israel: It was not because I need your light that I am telling you to light a lamp.⁶Below Numb. 3:7; Tanh. Numb. 3:2; Numb. R. 15:2. Rather <I am doing so> in order to have you acquire merit (by fulfilling a commandment), and so it says (in Is. 42:21): THE LORD WAS DELIGHTED BECAUSE OF HIS <SERVANT'S> RIGHTEOUSNESS. It is written about him, as it were, (in Dan. 2:22): HE KNOWS WHAT IS IN THE DARKNESS, AND THE LIGHT DWELLS WITHIN HIM; and similarly it says (in Ps. 139:12): EVEN DARKNESS IS NOT DARK TO YOU; [FOR NIGHT SHINES AS THE {LIGHT} [DAY], AND DARKNESS BECOMES LIKE THE LIGHT]. <Scripture says these things> to inform you that I do not need you. You yourself know <this truth>. Come and see. When a person builds a house and makes windows within [his house], he wants the light to enter. <So> he makes windows narrow on the outside and broad on the inside. Why? So that the light will enter from the outside and shine on the inside. But when Solomon built the Temple, he did not make the windows like that.⁷See above Exod. 8:5; PRK 21:5; Lev. R. 31:7. Rather they were narrow on the inside and broad on the outside so that the light would go out from the Temple and shine outside. It is so stated (in I Kings 6:4): AND FOR THE HOUSE HE MADE WINDOWS BROAD AND NARROW.⁸Literally: CLEAR and CLOSED. While the Hebrew is obscure the translation here follows the Targum in order to fit the midrashic context. <This text> is to inform you that all light is his and that he has no need for some of your <light>. So why did I command you <to set up the lamps>? In order to have you acquire merit (by fulfilling a commandment). It is therefore stated (in Numb. 8:2): WHEN YOU SET UP THE LAMPS.⁹Beha‘aloteka et-hanerot. These words can also mean: IN ELEVATING YOU WITH THE LAMPS. Ergo (in Is. 42:21): THE LORD WAS DELIGHTED BECAUSE OF HIS <SERVANT'S> RIGHTEOUSNESS. And not only that, but if you are careful to light lamps for my sake, I will shine a great light for you in the world to come, as stated (in Is. 60:1, 3): ARISE SHINE FOR YOUR LIGHT IS COME [….] AND NATIONS SHALL WALK BY YOUR LIGHT, EVEN KINGS BY THE BRIGHTNESS OF YOUR RISING.

"he is Mine": What is the intent of this? It is written (Devarim 15:19) "the male shall you sanctify to the L rd your G d." (How am I to understand this?) As sanctify it so that you receive reward, or if you sanctify it, it is sanctified, and, if not, it is not sanctified? It is, therefore, written "he is Mine" — in any event. What is the intent, then, of "the male shall you sanctify"? Sanctify it (i.e., dedicate it to the L rd) for the sake of receiving reward. Similarly, (Leviticus 6:5) "And the Cohein shall burn wood upon it every morning, etc." What is the intent of this? Is it not written (Isaiah 40:16) "and (the whole forest of Levanon is not sufficient to burn, etc."? What, then, is the intent of "And the Cohein shall burn wood upon it"? For the sake of receiving reward. Similarly, (Numbers 28:4) "the one lamb shall you offer, etc." What is the intent of this? Is it not written (Isaiah, Ibid.) "nor the beasts thereof sufficient for a burnt-offering"? What, then, is the intent of "The one lamb, etc."? For the sake of receiving reward. Similarly, (Exodus 25:8) "and they shall make for Me a sanctuary, etc." What is the intent of this? Is it not written (Jeremiah 23:24) "Do I not fill heaven and earth?" What, then, is the intent of "And they shall make for Me a sanctuary"? For the sake of receiving reward for making it. Once, the disciples spent a Sabbath in Yavneh, R. Yehoshua not among them. When they returned to him he asked them: "What novelty did you hear in Yavneh?" They answered: "After you, our master" (i.e., there is no one to do so after you). R. Yehoshua: "Who spent the Sabbath there?" They: "R. Elazar b. Azaryah." R. Yehoshua: "Is it possible that R. Elazar b. Azaryah spent the Sabbath there without telling you something novel?" They: He expounded this principle (Devarim 31:12) "Gather the people — the men, the women, and the children." Now do little children know the difference between good and evil? But (He did so) in order to bestow reward upon their bringers, to increase the reward of the doers of His will, as it is written (Isaiah 42:21) "The L rd desires for the sake of His righteousness to magnify Torah and to exalt it." At this, he said to them: "What can be more novel than this? I am seventy years old, and I never merited hearing such a thing until this day! Happy are you, father Abraham, from whose loins Elazar b. Azaryah emerged! The generation is not an orphan in whose midst R. Elazar b. Azaryah resides!" They: Our master, he also expounded this principle: (Jeremiah 23:7) "Therefore, behold, days are coming, says the L rd, when it will no more be said: 'As the L rd lives, who brought up the children of Israel from the land of Egypt, etc.'" To what may this be compared? A man desired children and had a daughter — whereupon (when he made a vow) he vowed upon her life. Thereafter, he had a son, and (in vowing) he left off (vowing by) his daughter and vowed upon the life of his son. R. Shimon b. Yochai says: To what may this be compared? A man was journeying and was accosted by a wolf, from which he was rescued — whereupon he would (always) talk about his encounter with the wolf. He was later accosted by a lion, from which he was rescued — whereupon he left off talking about his encounter with the wolf and spoke about his encounter with the lion. Similarly, (Genesis 29:19) "And he called the name of the place Beth-El." The first name was superseded by the second. Similarly, (Ibid. 17:5) "And your name will no longer be called Avram." The first name was superseded by the second. Similarly, (Ibid. 15) "Sarai, your wife, etc." The first name was superseded by the second. (Ibid. 32:28) "Your name will no longer be called Yaakov but Yisrael." The first name remained and the second was superadded. The name of Yitzchak was not changed, for he was thus (originally) called by the Holy One Blessed be He. There are three who were named by the Holy One Blessed be He — Yitzchak, Shlomoh, and Yoshiyahu. Yitzchak — (Ibid. 17:19) "But Sarah your wife will bear a son for you and you shall call his name Yitzchak." Shlomoh (I Chronicles 22:9) "for Shlomoh will be his name." Yoshiyahu (I Kings 13:2) "A son will be born to the house of David. Yoshiyahu will be his name." Others say: Also Yishmael among the gentiles. We find the names of righteous ones and their deeds to be revealed to the L rd before their creation, viz. (Jeremiah 1:5) "Before I created you in the womb, I knew you." Where do we find (the same for) the names of wicked ones? It is written (Psalms 58:4) "The wicked are estranged from the womb, etc."
