זוהר שמות — דף פז ע”ב

Rabbi Abba interprets the prohibition against making an idol as a ban on creating a Torah your teacher did not teach you. Rabbi Yitzhak explains it as a prohibition against betraying the brit mila covenant, the first bond between Israel and the Holy One. One who betrays this covenant betrays the Holy One Himself. Rabbi Elazar and Rabbi Hiya discuss the law of the beautiful captive and conclude that a woman from the nations is difficult to purify, and marrying her risks a rebellious son. Blessed is one who preserves his holy inheritance.
