Sforno on Exodus 23:13/ספורנו על שמות כ״ג:י״ג

1כל אשר אמרתי אליכם תשמרו, ושם אלוהימ אחרים לא תזכירו, the Israelites are cautioned not only not to violate G’d’s commandments, but to construct safeguards to ensure that they do not violate these commandments inadvertently. A prime example of this is the caution not to only not to worship idols, but not even to mention their names.

2לא ישמע על פיך, you must not even be the cause of others mentioning the names of these idols. If they do mention these names it must not be with your approval.
