וַיֹּאמֶר֩ אֵלִיָּ֨הוּ הַתִּשְׁבִּ֜י מִתֹּשָׁבֵ֣י גִלְעָד֮ אֶל־אַחְאָב֒ חַי־יְהוָ֞ה אֱלֹהֵ֤י יִשְׂרָאֵל֙ אֲשֶׁ֣ר עָמַ֣דְתִּי לְפָנָ֔יו אִם־יִהְיֶ֛ה הַשָּׁנִ֥ים הָאֵ֖לֶּה טַ֣ל וּמָטָ֑ר כִּ֖י אִם־לְפִ֥י דְבָרִֽי׃ (ס)
I rzekł Eljasz Tysbita, jeden z mieszkańców Gileadu, do Ahaba: Żyw Wiekuisty, Bóg Izraela, w którego służbie stoję, że nie będzie tych lat ani rosy, ani deszczu, chyba gdybym sam je zapowiedział.
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.”
