Kabbalah su Giobbe 19:78

Relating to what it says in the verse “Gird Your sword on Your thigh, O Mighty One” (Psalms 45:4), in our original explanation that the sword that avenges the revenge of the Covenant for someone who damages the Brit (Covenant), as it says at length in the Zohar in Va’era: 77. One day, Rabbi Chiya and Rabbi Yosi were before Rabbi Shimon. Rabbi Shimon opened the discussion saying, “Be afraid of the sword. For wrath brings the punishments of the sword, that you may know that there is a judgment” (Iyov 19:29). HE ASKS, It is written: “Be afraid of the sword.” What sword?

This sword, WHICH IS MALCHUT, stands to observe who is false to the covenant, WHICH IS YESOD, because anyone who is false to the covenant BLEMISHES IT WITH SEXUAL MISCONDUCT OR SPILLING SEMEN IN VAIN, it is this sword that takes vengeance on him. 78. This is the meaning of: “For wrath brings the punishments of the sword.” What is the reason? IT IS that anyone who is false to the covenant distances the desire OF MALCHUT TO RECEIVE SUSTENANCE FROM ZEIR ANPIN, and thus whoever should receive SUSTENANCE, NAMELY YESOD does not receive it, and does not give to his place, since his place, WHICH IS MALCHUT, is not awakened toward him. BECAUSE OF THE BLEMISH IN THE COVENANT THE DESIRE TO RECEIVE SUSTENANCE WAS TAKEN FROM HER.

As it says in the Zohar in Lech Lecha: 414. Hence the words, “from my flesh shall I see Eloha,” REFERRING TO THE NAME ELOHA, represent overall completion, because it is “from my flesh,” my own – WHICH IS YESOD THAT IS CALLED FLESH – the actual sign of the covenant. Therefore, happy are the holy Yisrael who are united with the Holy One, blessed be He; happy is their portion in this world and the World to Come. Of them, it is written: “You that cleave to Hashem your Elohim are alive every one of you this day” (Devarim 4:4).”...
