Midrash sur Rois 1 6:4

(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.

Another interpretation (of Exod. 27:20): AND YOU SHALL COMMAND <THE CHILDREN OF ISRAEL TO BRING UNTO YOU CLEAR OIL OF BEATEN OLIVES FOR THE LIGHT >…, not because I need light but in order to give you light. R. Johanan said: The eye is white with black in the middle.¹⁴Numb. R. 15:7. From where must it see? Not from the white? But that is not so. One only sees from the midst of the black. Now you are not able to comprehend the light of the eyes; yet you seek to comprehend my ways. Is it not because your <evil> drive misleads you, saying: Perhaps he (the Holy One) needs light? R. Abbin the Levite said: {You desire that whoever wants} [You find that whoever desires] to make windows for himself, makes them wider on the inside and narrower on the outside. Why? So that they will attract the light. But the windows of the Temple were wider on the outside and narrower on the inside.¹⁵Below, Numb. 3:2; also Lev. R. 31:7; cf. PRK 21:5, which deduces this assertion from I Kings 6:4. Why? So that the light would go forth from the Temple and light up the world. The light goes forth from the midst of my house; so do I have need of light? But you may say: Why does he need a lamp? In order to give us light. (Exod. 27:20:) TO BRING UNTO YOU CLEAR OIL OF BEATEN OLIVES…, in order to light up an eternal lamp so that your light may be constantly before me. David said (in Ps. 97:11:) LIGHT IS SOWN FOR THE RIGHTEOUS.
