The souls of Israelites come from the pure side, which is YHVH. Israelite men and women cannot connect with souls of the other side because as we explained in previous DZ study, the judgment will overcome the mercy.
To understand the soul of the Israelites we’ll go back to Abraham. He had the covenant with God and his soul was changed when God added the letter ה H to his name. From Abram he became Abraham. His wife, Sarah, was barren and God changed her soul too by changing her name from Sarai שרי to Sara שרה. They had a child, Isaac. Because Sarai couldn’t have children she wanted Abram to have a child from her maid. The child’s name was Ishmael and he was born to Abram before God changed his name and soul. The soul of Ishmael was mostly impure. He had only some merit from his father.
Isaac married Rivka, whose uncle was the evil Laban from Aram. Rivka was pure because she came to Isaac as a child and he waited for her to grow up before praying for her to be able to have children. They brought twin boys, Esau was to the left, and Jacob came out holding his ankle.
Jacob came out with a pure and complete soul. He made the major Tikkun of Adam by working 14 years to earn his connection to two wives, Lea and Rachel, Binah and Malchut. Jacob also fought and won over the angel of the other side to earn the name Israel. He was the third pure one in the line from Abraham and merited to be ‘fruitful’. He brought 12 children that are called the children of Israel. They carried the souls of all Israelites that will reincarnate until the final Tikkun and Final Redemption.
God took our patriarchs and matriarchs through a process of cleansing and refinement until Jacob so the Israelites can have the special soul that they have.
True and pure Israelite soul is capable of doing good and sharing without self serving agenda. If you connect to the Zohar with appreciation and love the Light, your soul is pure. If you feel that you expect something in return, a reward, a payment from God for following the Torah, then you better work hard to remove this negativity. The only reward an Israelite soul wants is to go back to the state of Adam in the Garden of Eden and experience immortality. That will happen only after Mashiach comes and start the process of the Final Redemption by cleansing the world from all negativity. After that we will experience the resurrection and immortality.
