Hebrew translation:

68. בֹּא רְאֵה, וְהָיָה שִׁבְעַת יָמִים וְגוֹ’. יוֹ”ד הֵ”א וָא”ו הֵ”א (וָא”ו הֵ”א יוֹ”ד הֵ”א) – נֶחְקְקוּ אוֹתִיּוֹת (וְהָיָה). ו’ ה’, הֲרֵי שִׁבְעַת יָמִים נִכְלְלוּ כְאֶחָד. י’ ה’, שִׁבְעַת יָמִים. י’ אֶחָד, הַכְּלָל שֶׁל הַכֹּל. ה’ שְׁלֹשָׁה, הִיא וּשְׁנֵי בָנִים. וּבֵן אֶחָד, שְׁנֵי אָבוֹת כְּלוּלִים בּוֹ – הֲרֵי שִׁשָּׁה (חֲמִשָּׁה). בַּת נְקֵבָה אַחַת – הֲרֵי שִׁבְעָה (שִׁשָּׁה). נִשְׁמָע שֶׁה’ עֶלְיוֹנָה כְּלָל שֶׁל שִׁשָּׁה. י”ה הֲרֵי שִׁבְעָה. הַיְנוּ שֶׁכָּתוּב (מלכים-א ח) שִׁבְעַת יָמִים וְשִׁבְעַת יָמִים אַרְבָּעָה עָשָׂר יוֹם.
69. וְהָיָה שִׁבְעַת יָמִים תַּחַת אִמּוֹ. תַּחַת אִמּוֹ, הִתְעַטְּרוּ שִׁבְעַת יָמִים, שֶׁכָּתוּב (דברי הימים-א כט) לְךָ ה’ הַגְּדֻלָּה וְהַגְּבוּרָה וְגוֹ’. וְעַל כֵּן שִׁבְעַת יָמִים לְמַטָּה לִכְבוֹד הָאֵם הָעֶלְיוֹנָה. תַּחַת אִמּוֹ לְמַטָּה, שֶׁכָּתוּב (שמואל-א ב) עַד עֲקָרָה יָלְדָה שִׁבְעָה וְרַבַּת בָּנִים אֻמְלָלָה. הָעִקָּר שֶׁל כָּל הַבַּיִת, יָלְדָה שִׁבְעָה, אֵלּוּ שִׁבְעַת הַיָּמִים שֶׁל חַג הַסֻּכּוֹת. וְרַבַּת בָּנִים אֻמְלָלָה – אֵלּוּ קָרְבְּנוֹת הֶחָג שֶׁיּוֹרְדִים בְּכָל יוֹם מִן הַמִּנְיָן.

Zohar Emor

#68
Leviticus 22:27
“שׁוֹר אוֹ כֶשֶׂב אוֹ עֵז כִּי יִוָּלֵד וְהָיָה שִׁבְעַת יָמִים תַּחַת אִמּוֹ וּמִיּוֹם הַשְּׁמִינִי וָהָלְאָה יֵרָצֶה לְקָרְבַּן אִשֶּׁה לַיהוָה.”
“When an ox or a sheep or a goat is born, it shall remain seven days under its mother, and from the eighth day on it shall be accepted as a sacrifice of an offering by fire to YHVH.”

The word ‘when’ is ‘וְהָיָה’ and it has the letters of YHVH יה וה. The Zohar explains that וה represents Zeir Anpin with its six sefirot and ה for Malchut and together with seven. The יה is also counted as seven. The י Y includes the four letters of the name and the ה is three for the יוד as explained previously. Together we have 14 as we read in 1 Kings 8:65
“וַיַּעַשׂ שְׁלֹמֹה בָעֵת-הַהִיא אֶת-הֶחָג וְכָל-יִשְׂרָאֵל עִמּוֹ קָהָל גָּדוֹל מִלְּבוֹא חֲמָת עַד-נַחַל מִצְרַיִם, לִפְנֵי יְהוָה אֱלֹהֵינוּ, שִׁבְעַת יָמִים, וְשִׁבְעַתיָמִים–אַרְבָּעָה עָשָׂר, יוֹם”
“So Solomon observed the feast at that time, and all Israel with him, a great assembly from the entrance of Hamath to the brook of Egypt, before YHVH our God, for seven days and seven more days, even fourteen days.”
After King Solomon finished the building of the Holy Temple and brought the Holy Ark into it, he made a 14 days celebration together with all the people throughout the land the connection they established to YHVH, with the aspects of seven upper and seven lower.

#69
‘it shall remain seven days under its mother’ is a rule to have a connection to the seven sefirot under the support and nourishment of the lower mother, ה of Malchut and for the honor of the supernal mother, upperה.
1 Samuel 2:5
“שְׂבֵעִים בַּלֶּחֶם נִשְׂכָּרוּ, וּרְעֵבִים חָדֵלּוּ, עַד-עֲקָרָה יָלְדָה שִׁבְעָה, וְרַבַּת בָּנִים אֻמְלָלָה”
“Those who were full hire themselves out for bread, But those who were hungry cease to hunger. Even the barren gives birth to seven, But she who has many children languishes.”
‘the barren gives birth to seven’ is the aspect of the seven days of the holiday of Sukkot when we receive the light of the sefirot of Zeir Anpin from Binah.
‘has many children languishes’ is the aspect of the 70 sacrifices that we offer as nourishment for the 70 nations of the world. The number of sacrifices is going down on each day of the holiday.

Lesson
The sages tell us that all ‘sevens’ are loved. It’ related to the purpose of Creation. God Created the system of the 10 Sefirot where three are on the pure supernal level and the lower seven is for the process of revealing the Light on the seventh sefira that is Malchut.
A week has seven days because this is how the seven sefirot control the cycle of the week. The six weekdays follow the six Sefirot and the seventh day is Shabbat where the supernal Light of Binah/the upper three is revealed on our level. It is when the love of God is expressed in this world.
The Holidays of Sukkot and Pesach have seven days because there’s a process of revealing great light in Malchut, the Seventh. There’s always a Shabbat during the seven days of the holiday.
Malchut has seven dimensions (worlds) and we are on the seventh level that is the highest and where we can reveal the most Light.
The seventh righteous Israelite that brought us the Torah was Moses (Abraham, Isaac, Jacob, Levi, Kehat, Amram, Moses).
