Kabbalah zu Schemot 20:4

It also says in the Tikkunei Zohar (66th Correction): Similarly, one who takes out from private domain to public domain, or one who transfers his seed from the sign of the holy Brit to a strange domain, it is as if he planted the Tree of Good and Evil. Therefore, one who implants in a Niddah, Maidservant, Gentile or Harlot, it says about him “You must not make for yourself an idol of any kind or an image” (Exodus 20:3) and a daughter that is formed from this conception is call a “idol”, and about them it says “Cursed is anyone who carves or casts an idol and conceals setting it up” (Deuteronomy 27:15), what is ‘concealed?’, this is the Concealed One of the world.
