אֲשֶׁר֩ יְדַבֵּ֨ר הַנָּבִ֜יא בְּשֵׁ֣ם יְהוָ֗ה וְלֹֽא־יִהְיֶ֤ה הַדָּבָר֙ וְלֹ֣א יָב֔וֹא ה֣וּא הַדָּבָ֔ר אֲשֶׁ֥ר לֹא־דִבְּר֖וֹ יְהוָ֑ה בְּזָדוֹן֙ דִּבְּר֣וֹ הַנָּבִ֔יא לֹ֥א תָג֖וּר מִמֶּֽנּוּ׃ (ס)
Cuando el profeta hablare en nombre del Señor y no fuere la tal cosa, ni viniere, es palabra que el Señor no ha hablado: con soberbia la habló aquel profeta: <span class="x" onmousemove="Show('perush','Este es el <b>29no Precepto Negativo</b> enumerado por el Rambam en el Prefacio a Mishné Torá, su “Compendio de la Ley Hebrea” para todo el Pueblo de Israel.',event);" onmouseout="Close();">no tengas temor de él</span>.
Sefer HaChinukh
That we not fear from the killing of a false prophet: That we not fear from killing a false prophet (see Mishneh Torah, Laws of The Sanhedrin and the Penalties within their Jurisdiction 14:3) and that we not fear that there be any punishment to us from this. And even if he prophesied about the fulfillment of the commandments - since there is falsehood in his mouth, we do not [receive] a punishment for his death; but rather it is a commandment upon us [to kill him]. And about this is it stated (Deuteronomy 18:22), "do not be afraid from him." And the language of Sifrei Devarim 178 is "'Do not be afraid from him' - do not prevent yourself from advocating guilt for him."
