“וַיֵּצֵא הָרִאשׁוֹן אַדְמוֹנִי כֻּלּוֹ כְּאַדֶּרֶת שֵׂעָר וַיִּקְרְאוּ שְׁמוֹ עֵשָׂו.”
“Now the first came forth red, all over like a hairy garment; and they named him Esau.”
Isaac was from the side of harsh judgment because he was from the Left of Zeir Anpin. His first seed was also from the left, represented by the red color. Esau came out “the first.” It doesn’t say ‘Esau came out first,’ allowing the thought that Jacob was the first seed, but Esau came first. Adding the ‘the’ to ‘first’ indicates that Esau was created from the first seed of Isaac. Esau came out red because Isaac was from the left Gevurah that is represented by the color red. The second drop was included from the Right and Left and created Jacob with the aspect of Mercy.
The two drops of Esau and Jacob were different. One was whole, and one was not. When Esau conceived, Isaac was meditating on the end of the harsh judgment that is the end of the Left line and the beginning of Gold waste that is the Klipot he releases from his side. Esau got connected to this impurity, which is the waste of the melted Gold.
We learned that the man needs to meditate at the time of the unification to be one with the will of God and to have righteous children. Isaac had pure meditation on the point where the Left line ends and its holiness. The first drop of seeds came out at that point, but it is still had judgments. It is written that Esau came out “red with a hairy garment.” We learned that judgments are called hair.
The consciousness at the time the man releases the seed together with the type of vessel the seed is planted into is crucial for the outcome. Isaac released the left with holiness and God created Esau from that left so the seed of Jacob will be a pure and balanced drop.
Abraham had two children, Ishmael came from the Klipa of Hagar that was the daughter of Pharaoh (Source: Rabbi Shimon בראשית רבה, לך לך, מה) and Isaac came from the purity of Sarah. Because God promised the child to Sarah, Isaac came out with a female type soul. Isaac had to go through the process of binding to have a new soul. Abraham had two children from two mothers. Isaac had two children from the same mother, but again one was from the impurity of the Left, and the other one came out pure. Jacob had four wives, and since he was from the middle line of balance, all his children came in righteousness.
Because Abraham and Isaac were righteous, they were channels for God to bring Jacob to the world and create balance in the spiritual system. After Jacob, the path was clear to bring the twelve tribes to strengthen the Tree of Life and channel light to the entire world.
