“חַיִּים שָׁאַל מִמְּךָ נָתַתָּה לּוֹ אֹרֶךְ יָמִים עוֹלָם וָעֶד”
“He asked life of You, You gave it to him, Length of days forever and ever.”
The life in this verse is related to King David’s life. When God create the Garden of Eden, he brought the soul of David. He saw that it didn’t have life and the soul was standing before him all the time.
After he created Adam he saw the life of Davin in Adam’s soul. These were the 70 years Adam gave David.
Another explanation to the life of David. The patriarchs Abraham, Jacob and Joseph gave from their lives to David. Isaac didn’t give because David came from his side, the Left.
King David is the aspect of the female of left column that is considered darkness and because of that he didn’t have life that comes only from the Right and the Tree of Life.
“וְאֵלֶּה תּוֹלְדֹת יִצְחָק, בֶּן-אַבְרָהָם: אַבְרָהָם, הוֹלִיד אֶת-יִצְחָק”
“These are the family records of Isaac son of Abraham. Abraham fathered Isaac.”
Isaac was from the Left and initially he had a female soul from the Left. The binding process transferred his soul to the ram that was found there to complete the death of Isaac’s soul, allowing him to receive a new soul from the Right. Abraham was from the Right and that is why the Torah states ‘Abraham fathered Isaac’
