Musar su Esodo 23:13

“Make no mention of the names of other gods” (Exodus 23:13) - a person should not say to his fellow, “Wait for me by idol x.”

Commandments 87 and 88 deal with the prohibition of swearing an oath in the name of some idolatrous deity and the law not to promote such deity in any form, since the Torah says: "Make no mention of other gods, nor let them be heard from your mouth" (23,13). Some think that the main prohibition is not to enter into business relations with idol worshippers on days that are holidays in their religion, since on such days the Gentile is bound to mention his idol and the Jew may inadvertently cause the Gentile to praise his deity. Since even Gentiles are prohibited from worshipping idols, this would be accounted a sin against the Jew causing it. Our sages have been so careful to ensure that we distance ourselves from such a sin that they forbade saying to a Gentile: "hold this package for me near the statue of such and such a deity" (Sanhedrin 63).
