Exodus 23:13

ובכל אשר אמרתי אליכם תשמרו AND IN ALL THAT I HAVE SAID TO YOU TAKE HEED — This statement is intended to bring every positive command (מצות עשה) also under the category of a prohibition (לאו); for wherever the term שמר, “take heed”, is used in the Torah it is an admonition in the place of (having the force of) a prohibition (cf. Yalkut Shimoni on Torah 355). לא תזכירו MAKE NO MENTION [OF THE NAME OF OTHER GODS] — This means that one must not say to another: “Wait for me near such-and-such an idol”, or, “Stay with me on the festival of such-an-such an idol’” (mentioning its name) (cf. Mekhilta; Sanhedrin 63b). Another explanation of verse 13 is: the juxtaposition of “Be heedful in respect of everything that I have spoken to you” with “and the names of other gods ye shall not mention” is intended to teach you that the practise of idol-worship is of equal heinousness as though one had infringed every command (cf. Horayot 8a); and that one who avoids it may be regarded as though he had observed every one of them (cf. Chullin 5a). לא ישמע IT SHALL NOT BE HEARD from a heathen, THROUGH THINE AGENCY — i. e. you shall make no business partnership with a heathen through which it might happen that he will take an oath by the name of his god, for consequently you will have brought it about that it has been mentioned through your agency (cf. Sanhedrin 63b).

וּבְכֹ֛ל אֲשֶׁר־אָמַ֥רְתִּי אֲלֵיכֶ֖ם תִּשָּׁמֵ֑רוּ וְשֵׁ֨ם אֱלֹהִ֤ים אֲחֵרִים֙ לֹ֣א תַזְכִּ֔ירוּ לֹ֥א יִשָּׁמַ֖ע עַל־פִּֽיךָ׃

And all things that I have said to you be mindful of: and make no mention of the name of other gods, neither let it be heard out of thy mouth.
