וְאִ֗ישׁ אֲשֶׁ֤ר יִנְאַף֙ אֶת־אֵ֣שֶׁת אִ֔ישׁ אֲשֶׁ֥ר יִנְאַ֖ף אֶת־אֵ֣שֶׁת רֵעֵ֑הוּ מֽוֹת־יוּמַ֥ת הַנֹּאֵ֖ף וְהַנֹּאָֽפֶת׃
Und ein Mann, der die Ehe bricht mit der Frau eines Mannes, mit dem Weibe seines Nächsten, beide sollen sterben: der Ehebrecher und die Ehebrecherin.
Zohar
When this happened to King David, fear enveloped him. Right then, Domeh ascended before the Creator, and said: “Master of the world, Master of the universe, in the Torah it says of "the man that commits adultery with another man's wife...the adulterer and the adulteress shall surely be put to death"' (Lev. 20:10). Furthermore, it is written, "Moreover, you shall not lie carnally with your neighbor's wife, to defile yourself with her" (Lev. 18:20). (So what is to become of) David, who has profaned his organ (of the holy covenant by committing a sexually immoral act)? The Holy One, blessed be He, said to him, "David is righteous! And the holy covenant remains intact, because it is known to Me that Bathsheba was assigned to him since the day the world was created.
