The Zohar mention two angels under the Holy Throne. The first one is Metatron and the second is Nuriel. Metatron escorts the Shechina with the King, YHVH.
The angel Nuriel נוריאל, was receiving the spiritual connections of the Israelites and bring it to the Holy One Blessed be He in a form of fire. The angel’s name begins with ‘נור’ that means fire.
When the Israelites went to exile, the Shechina move away from the King to be with the people and its light was gone and now depend on the work of the people in exile.
“לִינִי הַלַּיְלָה, וְהָיָה בַבֹּקֶר אִם-יִגְאָלֵךְ טוֹב יִגְאָל, וְאִם-לֹא יַחְפֹּץ לְגָאֳלֵךְ וּגְאַלְתִּיךְ אָנֹכִי, חַי-יְהוָה; שִׁכְבִי, עַד-הַבֹּקֶר”
“Remain this night, and when morning comes, if he will redeem you, good; let him redeem you. But if he does not wish to redeem you, then I will redeem you, as the LORD lives. Lie down until morning.”
This verse tells about the aspect of mercy, morning, as it says
“וַיַּרְא אֱלֹהִים אֶת-הָאוֹר, כִּי-טוֹב; וַיַּבְדֵּל אֱלֹהִים, בֵּין הָאוֹר וּבֵין הַחֹשֶׁךְ”
“God saw that the light was good; and God separated the light from the darkness.”
Light and ‘good’ are equal and when it says in the verse from Ruth above, ‘if he will redeem you, good’ it means that good and mercy will come to Ruth that is the aspect of Malchut and judgment.
Our studies and prayers are aspects of fire that rises above, create light, support the Shechina and draw mercy to our world of judgment.
