Kabbalah su Isaia 53:78

Since they brought it on you and did good things for you, you have suffered for their sakes many troubles so that Messiah the son of Joseph shall not be killed, of whom it says, "the face of an ox on the left side" (Ezekiel 1:10), who is a descendant of Joseph, of whom it says, "The firstling of his herd, grandeur is his" (Deuteronomy 33:17). That is because he and his descendants shall not be violated among the heathen nations because of the sin of Jeroboam who worshiped idols, for which he and his seed were to be violated among the idol worshiping nations. For Jeroboam the son of Nevat is a descendant of Joseph and it is because of him that it says of you, "But he was wounded because of our transgressions and by his injury we are healed" (Isaiah 53:5).

How much more so will he who fears the Lord (Exod. 9:20) give more love, awe, fear, and humility, will he worry because of his sins, and will he be concerned lest he increase his sins with the iniquity of erring in the statements [concerning] the knowledge of the holy God (Josh. 24:19) lest his soul offer itself in restitution (Isa. 53:10). His only recourse (Esther 4:11) and the territory of his inheritance (Deut. 32:9) is to strip himself, and to cut and offer [himself] as a complete sin offering.

The Lord alone will lead him, and there is no strange god with him (Deut. 31:12) who has apportioned to test in them and afflicted [them] because of their iniquities (Ps. 107.17).

Rabbi Yosi asks, Why are they there referred to as the firstborn and the younger, and here the elder and the younger? Rabbi Yosi said that they no longer have the power to do evil or arouse the Evil Inclination. This is understood from the verse, "the name of the elder (lit. 'bigger') was Leah" (Gen. 29:16), for she was weary (Heb. leah) from her wickedness and evil, while Rachel, "the younger (lit. 'smaller')," did not have the power to incite. As it is written, "and as a sheep (lit. 'Rachel') before her shearers is dumb" (Isaiah 53:7).

"Tries the Righteous" (Tehilim 11:5): What is the reason thereof? According to Rabbi Shimon, it is because the Holy One, blessed be He, wishes for the Righteous. As it is written, "But it pleased Hashem to crush him by disease" (Isaiah 53:10). This has already been explained. The Holy One, blessed be He, wishes for the soul and not the body, because the soul resembles the supernal soul (i.e. the Shechinah) and the body is not worthy of being united above. Thus, although the shape of the body is in the image of the supernal secret,
