גּ֤וּרוּ לָכֶ֨ם ׀ מִפְּנֵי־חֶ֗רֶב כִּֽי־חֵ֭מָה עֲוֺנ֣וֹת חָ֑רֶב לְמַ֖עַן תֵּדְע֣וּן שדין [שַׁדּֽוּן׃] (ס)
temei vós a espada; porque o furor traz os castigos da espada, para saberdes que há um juízo.
Zohar
AND THE LORD SPOKE UNTO MOSES SAYING, THIS SHALL BE THE LAW OF THE LEPER. R. Abba cited here the verse: “Be ye afraid of the sword, for wrath bringeth the punishments of the sword, that ye may know there is a judgement” (Job 19, 29). ‘Observe,’ he said, ‘that through the evil tongue of the serpent death came upon the world. The evil tongue is called a “sharp sword” (Ps. 57, 5), and therefore it says, “Be ye afraid of the sword”, to wit, of the evil tongue. Why? “For wrathful are the punishments of the sword”, to wit, the sword of the Lord, “that ye may know there is a judgement”, for he that hath a sword in his tongue is punished with the sword; hence it says, “this is the law of the leper”.’
Reshit Chokhmah
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? HE ANSWERS, This is “a sword…that shall avenge My covenant” (Vayikra 26:25). 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.
