4. The sheath of the sword, THE CONTAINER WHERE THE SWORD IS HIDDEN, is the name Adonai. There IN ADONAI, the letters of Judgments are found, SINCE IN ADONAI ARE THE LETTER ALEPH AND DIN (ENG. 'JUDGMENT'). In the reading of Sh'ma is the secret meaning of Yud Hei Vav Hei, that is the sword of the Holy One, blessed be He, AS MENTIONED ABOVE. About it, it is written: "The high praises of Elohim in their throat, and a two edged sword in their hand" (Tehilim 149:6), AS WAS EXPLAINED ABOVE. In the righteous, the life of the world, are included all the eighteen blessings, MEANING THAT THROUGH THE RIGHTEOUS, YESOD OF ZEIR ANPIN, IS ACCOMPLISHED THE UNION OF ZEIR ANPIN AND MALCHUT OF GREATNESS, WHICH IS THE SECRET OF THE EIGHTEEN BLESSINGS IN THE AMIDAH PRAYER. In it, "Adonai my lips open, and my mouth" (Tehilim 51:17) "My mouth," MEANS THAT YESOD OPENS MALCHUT, WHICH IS CALLED 'ADONAI.' In it, IN YESOD, the sword enters into its sheath. THAT IS THE MEANING OF THE UNION OF YUD HEI VAV HEI WITH ADONAI THAT IS ACCOMPLISHED THROUGH YESOD. "Then the king's wrath was pacified" (Ester 7:10), BECAUSE THE KLIPOT WERE CONSUMED BY THE UNIFICATION OF THE READING OF SH'MA. NOW BY THE AMIDAH PRAYER, THEY NO LONGER HAVE A HOLD AND THE ANGER SUBSIDES. The two names are joined, Yud-Aleph-Hei-Dalet-Vav-Nun-Hei-Yud, WHICH IS THE INTEGRATION OF THE TWO NAMES YUD HEI VAV HEI AND ADONAI.
