“וַיֹּאמֶר יְהוָה, אֶל-מֹשֶׁה, עַתָּה תִרְאֶה, אֲשֶׁר אֶעֱשֶׂה לְפַרְעֹה: כִּי בְיָד חֲזָקָה, יְשַׁלְּחֵם, וּבְיָד חֲזָקָה, יְגָרְשֵׁם מֵאַרְצוֹ. ”
“Then YHVH said to Moses, “Now you shall see what I will do to Pharaoh; for under compulsion he will let them go, and under compulsion he will drive them out of his land.””
The above is the last verse from the portion of Shemot where God (YHVH) promise the Redemption from Egypt.
“וַיְדַבֵּר אֱלֹהִים , אֶל-מֹשֶׁה; וַיֹּאמֶר אֵלָיו, אֲנִי יְהוָה ”
“God (אֱלֹהִים, ELOHIM) spoke to Moses and said to him, “I am the LORD (יְהוָה YHVH).”
Then God with the aspect of judgment comes to Moses to tell that the decree over the Egyptian has been made and now God in the aspect of Mercy (YHVH) is on the side of the Israelites.
“וָאֵרָא, אֶל-אַבְרָהָם אֶל-יִצְחָק וְאֶל-יַעֲקֹב–בְּאֵל שַׁדָּי; וּשְׁמִי יְהוָה, לֹא נוֹדַעְתִּי לָהֶם”
“and I appeared to Abraham, Isaac, and Jacob, as God Almighty (אֵל שַׁדָּי), but by My name, YHVH, I did not make Myself known to them.”
God (YHVH) explains to Moses that he revealed himself to Abraham, Isaac and Jacob only at the level of ‘God Almighty’ that is the name “אֵל שַׁדָּי”. This name represents God at the level of Chessed that is the bridge to Binah and the upper light and from Yessod to Malchut.
Now it’s time for the complete revelation of YHVH on all the levels below Binah, bringing the light to Zeir Anpin and closer to the people. That was done after the Exodus in Mount Sinai when the Israelites received the Torah.
“וְגַם הֲקִמֹתִי אֶת-בְּרִיתִי אִתָּם, לָתֵת לָהֶם אֶת-אֶרֶץ כְּנָעַן–אֵת אֶרֶץ מְגֻרֵיהֶם, אֲשֶׁר-גָּרוּ בָהּ.”
“I also established my covenant with them to give them the land of Canaan, the land in which they lived as sojourners.”
The covenant that God promised the fathers will be fulfilled when God takes them from Egypt to the Promised Land. They will experience the ultimate unification of the Light and Vessel, Zeir Anpin (YHVH) and Malchut (the Promised Land).
Each one of the different names of God in the Torah represents a level of revelation of the Endless light. The Endless Light sustains the entire Tree of Life and each Sefira has a holy name that governs it.
When the Final Redemption arrives we will experience the light of the Entire Tree of Life without the levels of the lower seven Sefirot. The name that will control everything is going to be a new one. Because the seven Sefirot will be full of light and no process to follow for achieving it. The prophet Zechariah hints that the new name will be YHYH.
“וְהָיָה יְהוָה לְמֶלֶךְ, עַל-כָּל-הָאָרֶץ; בַּיּוֹם הַהוּא, יִהְיֶה יְהוָה אֶחָד–וּשְׁמוֹ אֶחָד”
“And YHVH will be king over all the earth. On that day YHVH will be (YHYH) one and his name one”
