Holy Zohar text. Daily Zohar -333.

Tikkun 21-74

Ruth 3:13
“לִינִי הַלַּיְלָה, וְהָיָה בַבֹּקֶר אִם-יִגְאָלֵךְ טוֹב יִגְאָל, וְאִם-לֹא יַחְפֹּץ לְגָאֳלֵךְ וּגְאַלְתִּיךְ אָנֹכִי, חַי-יְהוָה; שִׁכְבִי, עַד-הַבֹּקֶר”
“Dwell in the night; and when the morning becomes present if you will be redeemed – good will redeem. And if redemption is manifested, I am your redeemer, YHVH Live; lie down until the morning.” (Translated by me)

The story of Ruth is about forming the seed of the Final Redemption.
The Zohar reveals the secret of this verse and explains that the morning refers to right column, the light of Chessed that will be revealed at the end of the night, which is the aspect of the last exile.
I am, אנכי is the name of Holy One Blessed be He, at the time of the Exodus. It is the first word that opens the 10 commandments. It represents the supernal mother that will bring the redemption with the light of the right column and control the left column to establish the central column forever.
