Midrash su Genesi 30:38

[(Exod. 27:20:) AND YOU SHALL COMMAND….] This text is related (to Cant. 7:6 [5]): YOUR HEAD UPON YOU IS LIKE CARMEL, <AND THE LOCKS (dallah) OF YOUR HEAD (rosh) ARE LIKE PURPLE>. The poor (dallim) and the needy (rashim) who are among you are as dear to me as Daniel.⁸See Tanh., Exod. 8:6; Lev. R. 31:4; Cant. R. 7:6:1, all of which cite Dan. 5:29: AND THEY CLOTHED DANIEL IN PURPLE. [(Ibid., cont.:) A KING IS CAPTIVATED BY THE TRESSES (rehatim).] The Holy One, as it were, said to them: I am bound <by an oath>⁹The added words appear in all the parallel versions except Yalqut Shim’oni, Cant., 992. to be among you. By virtue of what? By virtue of the races that Abraham ran for me, as stated (in Gen. 18:6–7): ABRAHAM HASTENED TO THE TENT <…> THEN ABRAHAM RAN UNTO THE HERD.¹⁰On the three races of Abraham, see above, Tanh. (Buber), Gen. 4:5, and the note there. Ergo (in Cant. 7:6 [5]): A KING IS CAPTIVATED BY THE TRESSES (rehatim).¹¹The root of rehatim (i.e., RHT) can mean “run.” R. Levi said: By virtue of Jacob, of whom it is written (in Gen. 30:38): < AND HE SET UP THE RODS WHICH HE HAD PEELED> IN THE TROUGHS (rehatim), IN THE WATER RECEPTACLES.

“Your head is upon you like the Carmel, and the locks of your head are like purple wool; the king is bound in the tresses” (Song of Songs 7:6).
“Your head is upon you like the Carmel,” the Holy One blessed be He said to Israel: “Your head [roshekh] is upon you like the Carmel”—the indigent [rashim] among you are as dear to Me as Elijah who climbed Mount Carmel, as it is stated: “Elijah climbed to the peak of the Carmel and he placed his face between his knees” (I Kings 18:42). Why did he place his face between his knees? He said before the Holy One blessed be He: We have no merit, look to the covenant.⁴⁰He put his head between his knees as an allusion to the covenant of circumcision.
“And the locks [dalat] of your head [roshekh] are like purple wool.” The Holy One blessed be He said: The poor [dalim] and the indigent [rashim] in Israel are as dear to me as David, as it is stated: “The feeble among them will on that day be like David” (Zechariah 12:8). Some say like Daniel, about whom it is written: “They clothed Daniel in purple wool” (Daniel 5:29).
“The king is bound in the tresses,” this is the King of kings, the Holy One blessed be He, in whose regard it is written: “The Lord reigns, He is clothed in grandeur” (Psalms 93:1). “Bound in the tresses [barehatim],” as He bound Himself with an oath that He would rest His Divine Presence in the midst of Israel, in the beams [barehatim] of Jacob our patriarch. By whose merit? Rabbi Abba bar Kahana and Rabbi Levi, one said: By the merit of Abraham our patriarch, as it is stated: “Abraham ran⁴¹The Aramaic translation of “ran” is rahat. to the cattle” (Genesis 18:7). And one said: By the merit of Jacob our patriarch, in whose regard it is written: “He displayed the rods [that he had peeled in the troughs [barehatim]]” (Genesis 30:38).
Rabbi Berekhya said: “King,” this is Moses, as it is stated: “He became king in Yeshurun” (Deuteronomy 33:5). “In the tresses [barehatim],” as it was decreed upon him that he would not enter the Land of Israel.⁴²In that sense Moses was “bound” by the decree against him. For what reason? It was due to the water troughs [barehatim] of the waters of contention. That is what is written: “They are the waters of contention” (Numbers 20:13). Rabbi Neḥemya said: “King,” this is Moses, as it is stated: “He became king in Yeshurun” (Deuteronomy 33:5). The Holy One blessed be He said to Moses: ‘I appointed you king over Israel and it is the way of a king to issue decrees and have others fulfill them. Thus, you shall issue decrees upon Israel and they will fulfill them.’ That is what is written: “Command the children of Israel” (Leviticus 24:2).

According to the explanation of R. Abba the son of Kahana, The king is held captive in the tresses applies to Jacob. It is written concerning him: And he set the rods which he had peeled over against the flocks in the gutters (barhatim) in the watering-troughs (ibid. 30:38). Hence The king is held captive in the tresses thereof. The Holy One, blessed be He, said to Moses: I will make you a king, and just as a king’s people fulfill his decrees, so when you decree they will fulfill it.

Another interpretation of "Command the Children of Israel" (Leviticus 24:2): Bar Kapparah opened [his discourse]: "It is You who light my lamp" (Psalms 18:29) - the Holy One, blessed be He, said to Adam, "Your light is in My hands and My light is in your hands." Your light is in My hands, as it is stated (Proverbs 20:27), "The lamp of the Lord is the soul of man"; and My light is in your hands, as it is stated (Leviticus 24:2), "to light a continual lamp." Rather, the Holy One, blessed be He, said, "If you light My lamp, I will certainly light your lamp." This is [the understanding of] "Command the Children of Israel" (Leviticus 24:2). This is [the understanding of] that which is written (Song of Songs 7:6), "Your head (roshekha) upon you is like crimson wool (karmel), the locks of your head are like purple" - the Holy One, blessed be He, said to Israel, "The poor (rashim) among you are as beloved to Me as Eliyahu, when he went up to [Mount] Carmel." This is [the understanding of] "and Elijah climbed to the top of Mount Carmel, crouched on the ground, and put his face between his knees." And why did he put his face between his knees? He said, "Master of the world, if we do not have any merit, look to the covenant of circumcision." "The locks (dalat) of your head are like purple" (Song of Songs 7:6) - the Holy One, blessed be He, said, "The indigent (dalim) among you are beloved to me like David, as it is stated (Zechariah 12:8), 'and the feeblest of them shall be in that day like David.'" And some say, "Like Daniel, as it is stated (Daniel 5:29), 'they clothed Daniel in purple.'" "A king is held captive in the tresses (rehatim)" (Song of Songs 7:6) - the Holy One, blessed be He, bound Himself with an oath that he has His Divine Presence dwell within the boards (rehitin) of Yaakov our father. In whose merit? Rabbi Abba bar Kahana said, "In the merit of Avraham our father, as it is written (Genesis 30:38), 'And Avraham ran (which in Aramaic is rahat) to the cattle.'" Rabbi Levi said, "In the merit of Yaakov, as it is written (Geneis 30:38), 'The rods that he had peeled he set up in the troughs (rehatim).'" Rabbi Berakhiah said, "'A king is held captive in the tresses'" - that is [referring to] Moshe. For about him is it written (Deuteronomy 33:5), 'And he was a king in Yeshurun'; 'in the tresses (rehatim),' as the Holy One, blessed be He, decreed upon him that he would not enter the land. Because of [what]? Because of the troughs of the Waters of Merivah. This is [the understanding of] that which is written (Numbers 20:13) 'These are the waters of Meribah upon which the Children of Israel quarreled.'" Rabbi Yehudah [said], "They compared this to a parable: To what is this thing similar? To a king that made a decree and said, 'Anyone who plucks and eats fruits of the seventh-year [that are forbidden] will be placed upon the [town] platform.' A women of noble lineage came and plucked and ate from fruits of the seventh-year. [So] they began to place her on the platform. She was [then] yelling out, 'I plead with you, my master the king, hang these unripe figs from my neck so that the creatures do not say, "It appears to us that there is a matter of licentiousness or a matter of sorcery with her." Rather from that which they see the unripe figs on my neck, they will know that I am placed [here] on account of them.' So did Moshe say in front of the Holy One, blessed be He. 'Master of the world, write in Your Torah why I am not entering the Land, so that Israel will not say, "It appears to us that Moshe forged the Torah or said something that he was not commanded."' The Holy One, blessed be He, said, 'By your life, I shall write that it was only for the water.'" This is [the understanding of] that which is written (Numbers 27:14), "as you rebelled against My [word] in the Wilderness of Tsin." Rabbi Shimon [said], "They compared this to a parable: To what is this thing similar? To a king, when the king was on the road and his son was with him in a carriage. When they reached a narrow place, the carriage overturned on his son. His eye was blinded, his hand was cut off [and] his foot was broken. When the king would reach that place, he would remember and say, 'His eye was blinded here; his hand was cut off here, his foot was broken here.' So [too] the Holy One, blessed be He, mentions the Waters of Merivah three times in His Torah, meaning to say, 'I killed Moshe here; I killled Aharon here; I killed Miriam here.'" This is [the understanding of] that which is written (Psalms 141: 6), "May their judges slip on the rock, but let my words be heard, for they are sweet." Rav Nachman said, "'A king' - that is [referring to] Moshe, as it is written (Deuteronomy 33:5), 'And he was a king in Yeshurun.' The Holy One, blessed be He, said 'I have appointed you king over Israel. The way of a king is to decree and others observe [his decree]. So [too] shall you decree and Israel observe [it].'" This is [the understanding of] that which is written, "Command the Children of Israel" (Leviticus 24:2).
