Torah, “Deuteronomy,” 7:02 – 7:04: Neither shall you make a covenant with them (with other nations), nor be gracious to them. You shall not intermarry with them; you shall not give your daughter to his son, and you shall not take his daughter for your son. For he will turn away your son from following Me, and they will worship the gods of others, and the wrath of the Lord will be kindled against you, and He will quickly destroy you.
A person can’t make any concessions with egoism, no connection, no partial solutions. He should completely kill egoism, rise above it, stop using it in its natural form, and use it only after the first restriction with the screen, with the Returning Light, for bestowal and love.
Question: What does it mean “you shall not take his daughter for your son”?
Answer: Do not leave anything of egoistic origin that eventually will manifest in you as your corrupted quality. Then you will lose connection with the Creator and won’t be able to continue fighting for the purity of your correction and rise spiritually.
To marry a son to a daughter of an alien people means to allow some contact with egoism in the future. There can’t be the Creator in this action. Therefore it is said that it “will turn away your son from following Me, and they will worship the gods of others.”
