וְהָ֤יְתָה לּוֹ֙ וּלְזַרְע֣וֹ אַחֲרָ֔יו בְּרִ֖ית כְּהֻנַּ֣ת עוֹלָ֑ם תַּ֗חַת אֲשֶׁ֤ר קִנֵּא֙ לֵֽאלֹהָ֔יו וַיְכַפֵּ֖ר עַל־בְּנֵ֥י יִשְׂרָאֵֽל׃
Lui et sa postérité après lui posséderont, comme gage d’alliance, le sacerdoce à perpétuité; parce qu’il a pris parti pour son Dieu et procuré expiation aux enfants d’Israël."
Sha'arei Orah
Now, in the Torah, HaShem’s-יהו"ה quality as the Living God-El Chai-א"ל חי is sometimes called Covenant-Brit-ברית. Know and understand that every term of covenant-ברית in Torah divides into three kinds of matters that are all connected as one. The three matters divide into these three names; Lord-Adona”y-אדנ"י, the Living God-El Chai-א"ל חי and Understanding-Binah-בינה. The covenant of Understanding-Binah-בינה is the covenant of the mouth, the covenant of the tongue and the covenant of the lips, as it states,131Exodus 34:27 “upon the mouth-Al Pee-על פי of these things I have made a covenant with you.”132The words “Al Pee-על פי-upon the mouth,” is how “according to” is said in the Hebrew language. Thus, the usual translation of this verse is, “According to these things I have made a covenant with you.” The covenant of the Living God-El Chai-א"ל חי is called the covenant of Peace-Shalom-שלום, as stated,133Numbers 25:13 “Behold, I give him My covenant of Peace-Breetee Shalom-בריתי שלום,” which includes the covenant of Shabbat and the covenant of the rainbow. Moreover, HaShem-יהו"ה, blessed is He, gave us the covenant of circumcision-Brit Milah-ברית מילה so that we can merit His quality as the Living God-El Chai-א"ל חי. The covenant of HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י corresponds to the covenant of the Torah, which is bound between the covenant of the Living God-El Chai-א"ל חי and the covenant of the Lord-Adona”y-אדנ"י. When HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י is bound to His quality as the Living God-El Chai-א"ל חי and to His quality of Understanding-Binah-בינה, then it too is called by the term covenant-Brit-ברית, in accordance to both. This is the matter of the covenant of the tongue and the covenant of the skin (circumcision).
Zohar Chadash
“In the beginning (Bereishit), God created” (Genesis 1:1): Rabbi Abba began and said: “On that day. the Lord made a covenant with Avram, saying” (Genesis 15:18). The covenant was said about five things: The first is circumcision, as it is stated (Genesis 17:13), “this shall be My covenant in your flesh as an eternal covenant.” The second is the rainbow, as it is stated (Genesis 9:13), “and it shall be a sign of the covenant.” The third is the covenant of salt, as it is stated (Numbers 18:19), “an everlasting covenant of salt.” The fourth is the covenant of afflictions, as it is stated (Deuteronomy 28:69), “These are the words of the covenant.” The fifth is the covenant of the priesthood, as it is stated (Numbers 25:13), “And it shall be for him, and for his offspring after him, an everlasting covenant of priesthood.”
