וָאֶשְׁמַ֞ע אֶת־הָאִ֣ישׁ ׀ לְב֣וּשׁ הַבַּדִּ֗ים אֲשֶׁ֣ר מִמַּעַל֮ לְמֵימֵ֣י הַיְאֹר֒ וַיָּ֨רֶם יְמִינ֤וֹ וּשְׂמֹאלוֹ֙ אֶל־הַשָּׁמַ֔יִם וַיִּשָּׁבַ֖ע בְּחֵ֣י הָעוֹלָ֑ם כִּי֩ לְמוֹעֵ֨ד מֽוֹעֲדִ֜ים וָחֵ֗צִי וּכְכַלּ֛וֹת נַפֵּ֥ץ יַד־עַם־קֹ֖דֶשׁ תִּכְלֶ֥ינָה כָל־אֵֽלֶּה׃
И я услышал человека, одетого в льняное, который был над водами реки, когда он поднял правую руку и левую руку к небу и поклялся Им, живущим вовек, что будет время, времена, и половина; и когда они покончат с разрушением силы святого народа, все это закончится.
Sha'arei Orah
From this we learn that the oath-Shevuah-שבועה is in HaShem’s-יהו"ה quality as the Living God-El Chai-א"ל חי which is the secret of the seventh-Shevi’ee-שביעי, which is the matter of Shabbat, which is the matter of the life of the soul-Chayay HaNefesh-חיי הנפש, which is the matter of “He ceased and His soul was refreshed-Shabbat VaYinafash-שבת וינפש. Furthermore, since the oath-Shevuah-שבועה is in HaShem’s-יהו"ה quality as the Living God-El Chai-א"ל חי, it says about this matter,164Daniel 12:7 “He lifted his right and left [hands] to the heavens and swore by the Life of the world-Chay HaOlam-חי העולם.” As you see, the oath-Shevuah-שבועה is in the Life of the world-Chay HaOlam-חי העולם, which is HaShem’s-יהו"ה quality as the Living God-El Chai-א"ל חי. Moreover, in other verses it states,165Kings I 17:1 “By the life of HaShem-יהו"ה, the God of Israel, before whom I stood etc.,” and166Kings II 2:2 “By HaShem who lives-Chai HaShem-חי יהו"ה and by the life of your soul-V’Chey Nafshecha-וחי נפשך, I will not leave you,” and167Samuel I 1:26 “By your life, my master-Chay Nafshecha Adonee-חי נפשך אדני.”
Sha'arei Orah
It therefore stands “within the garden-b’Toch HaGan-בתוך גן,”437Genesis 2:9 – “Also, the Tree of Life-Etz HaChayim-עץ החיים within the Garden-Gan-גן, and the Tree of Knowledge of Good and Bad.” That is, about the Tree of Life the verse specifies that it is within the Garden-Gan-גן, and then goes on to mention the Tree of the Knowledge of good and evil, indicating that, unlike the Tree of Life, it is not within the Garden-Gan-גן. which Onkelos, peace be upon him, translates as, “In the center of the Garden-bMetziyut Ginta-במציעות גנתא,”438It is noteworthy that all the translations of Onkelos were received as a direct Kabbalah from Rabbi Eliezer and Rabbi Yehoshua. See Talmud Bavli, Megillah 3a. in that it is the middle line-Kav HaEmtza’ee-קו האמצעי, as explained. By means of this tree-Etz-עץ there is a union of understanding-Binah with kingship-Malchut, because the two letters Hey-ה of the Singular Name HaShem-יהו״ה are unified with the middle line-Kav HaEmtza’ee-קו האמצעי, one above and one below. The upper one is called life-Chayim-חיים, and is the secret of the life of the coming world (Chayei Olam HaBa-חיי עולם הבא), and is hinted in the verse,439Daniel 12:7 “And he swore by the Life of the World-Chey HaOlam-חי העולם.” In contrast, the “Life of the Worlds-Chey HaOlamim-חי העולמים” [in the plural] is the quality of foundation-Yesod, which is the foundation of life-Yesod HaChayim that draws from the Tree of Life-Etz HaChayim-עץ החיים, meaning, from understanding-Binah. They all are drawn from the middle line-Kav HaEmtza’ee-קו האמצעי, which is the trunk of the tree, until they reach the quality of foundation-Yesod, which is then called the “Life of the Worlds-Chey HaOlamim-חי העולמים.”
