“וְאַף גַּם זֹאת בִּהְיוֹתָם בְּאֶרֶץ אֹיְבֵיהֶם לֹא מְאַסְתִּים וְלֹא גְעַלְתִּים לְכַלֹּתָם לְהָפֵר בְּרִיתִי אִתָּם כִּי אֲנִי יְהוָה אֱלֹהֵיהֶם”
“’Yet in spite of this, when they are in the land of their enemies, I will not reject them, nor will I so abhor them as to destroy them, breaking My covenant with them; for I am YHVH their God.”
Rabbi Yosei quotes this verse and explains that we see here the connection of Zeir Anpin and Malchut. Even when we are in exile, God won’t break the connection with his people in order to keep the covenant with them. Severing the connection/covenant between Zeir Anpin and Malchut means disconnecting the source of light from Malchut, which means total destruction/death of Malchut, this world.
Rabbi Chiya brings an explanation that he heard from Rabbi Elazar. The word ‘to destroy’ in the verse above spelled ‘לְכַלֹּתָם’, missing the letter Vav, ‘ו’. It gives the word another meaning that is ‘their Bride’, which is reference to the Shechina.
The reason that God didn’t reject or abhor them is because they had his beloved bride, the Shechina with them.
