תַּֽחַת־עֶ֭בֶד כִּ֣י יִמְל֑וֹךְ וְ֝נָבָ֗ל כִּ֣י יִֽשְׂבַּֽע־לָֽחֶם׃
le spectacle de l’esclave qui devient roi, le spectacle du scélérat qui vit dans l’abondance:
Or HaChaim
The Torah refers to two different kinds of worship of another deity. One kind of worship is that by a person who really believes that such a deity is real and he yearns to worship it. Concerning such a person the Torah says: "do not make with Me אלוהי כסף, a deity you yearn to worship. Inasmuch as the soul of the Israelite is rooted in the celestial spheres and as such is part of G'd, if a person worships another deity also in his heart, he is so to speak attaching some of that deity to G'd Himself. The author bases all this on both Deut. 32,9 and on the mystical aspect of a statement in Eycha Rabbah 1,31 according to which the original serpent is holed up in a tower and the question is how to dislodge it without destroying the tower in the process. The answer suggested is that one calls on the services of a snake charmer so as to lure the snake out of its lair. When a person serves idols with all his heart he allows Satan to lodge within the very root of his being (like in the Tower in the story in the Midrash). This root of a person, i.e. his soul, is a sacred place, however. Solomon refers to such a tragic situation when he speaks of the slave turned master in Proverbs 30,22. When the Torah speaks of לא תעשון אתי אלוהי כסף, it refers to deities one serves because of a genuine conviction, longing.
