Targum Pseudo-Jonathan on Exodus (Exodus 23:13) gives an unusual command: of all the precepts that I have spoken to you, be careful; and the names of the idols of the Gentiles remember not, nor let them be heard upon your lips.
This is not merely a prohibition against worship. It is a prohibition against speech. Do not pronounce their names. Do not mention them in jest. Do not use them as landmarks.
Why Speech Matters So Much
The Torah understands that names carry weight. To name something is to give it a place in your mental world. A god whose name you say casually becomes a god you think about casually. Over generations, this familiarity slides into tolerance, and tolerance into worship.
The rabbis extended this ruling into daily practice. Do not say I will meet you by the temple of so-and-so, using the idol as a landmark. Find another way to describe the location. The Torah is training Jewish mouths to speak only the Name that matters.
The Broader Principle
The Targum opens the verse with a general charge: of all the precepts that I have spoken to you, be careful. Then it narrows to idolatry. This is the Torah's way of saying: the whole covenant depends on this one thing. Every mitzvah you keep is a consequence of the first commandment. Every mitzvah you abandon is a prelude to idolatry.
The Takeaway
Language shapes loyalty. The Torah commands a Jewish mouth to keep certain names alive and let others fade into silence.
