Not to be afraid of killing the false prophet

The Luchos - Ten Commandments
אֲשֶׁר֩ יְדַבֵּ֨ר הַנָּבִ֜יא בְּשֵׁ֣ם יְהֹוָ֗ה וְלֹֽא־יִהְיֶ֤ה הַדָּבָר֙ וְלֹ֣א יָבֹ֔א ה֣וּא הַדָּבָ֔ר אֲשֶׁ֥ר לֹא־דִבְּר֖וֹ יְהֹוָ֑ה בְּזָדוֹן֙ דִּבְּר֣וֹ הַנָּבִ֔יא לֹ֥א תָג֖וּר מִמֶּֽנּוּ׃ - פָּרָשַׁת שׁוֹפְטִים
Deuteronomy 18:22 - "If the prophet speaks in the name of the Lord, and the thing does not occur and does not come about, that is the thing the Lord did not speak. The prophet has spoken it wantonly; you shall not be afraid of him."

This Mitzvah's Summary

מִצְוָה עֲשֵׂה - Positive Commandment
מִצְוָה לֹא תַעֲשֶׂה - Negative Commandment
Prophecy – נְבוּאָה

It is forbidden to fear or refrain from carrying out judgment against a false prophet.

This mitzvah commands Israel not to be intimidated by the presence, charisma, or threats of a false prophet. If his words are proven false, he must be executed according to Torah law. Rambam (Hilchot Yesodei HaTorah 10:4) explains that Beit Din is warned not to hesitate in judging him out of awe, fear, or reverence, for allowing him to live endangers Torah’s truth.

The Talmud (Sanhedrin 89a) states that once a prophet is tested and proven false, his punishment is death, and the people must not be cowed by his reputation or following. Sefer HaChinuch (Mitzvah 518) explains that this mitzvah strengthens Israel’s resolve, reminding them that Torah’s truth is higher than any man’s charisma. Rashi (Deut. 18:22) emphasizes that “do not fear him” means both not fearing his words and not fearing to carry out his sentence. Ramban adds that this mitzvah protects communal faith from corruption, for hesitation in punishing him emboldens deceit. Midrash (Sifrei Devarim 178) notes that Israel is tested with figures of influence, but Torah instructs courage to uphold truth.

Commentary & Classical Explanation:

  • Rambam (Yesodei HaTorah 10:4): Beit Din must not hesitate in judging a false prophet.
  • Sefer HaChinuch (518): Strengthens Israel’s resolve against charismatic falsehood.
  • Talmud (Sanhedrin 89a): Execution must follow once falsity is proven.
  • Rashi (Deut. 18:22): “Do not fear him” applies to both his speech and his punishment.
  • Ramban: Hesitation emboldens false prophecy.
  • Midrash (Sifrei Devarim 178): Courage in judgment is a test of fidelity to Hashem.

Contrast with Mitzvah 43 (Not to listen to a false prophet):

  • Mitzvah 43 prohibits the people from heeding him.
  • Mitzvah 45 prohibits fearing him when judgment is due.
  • Rambam explains that Torah closes all gaps: don’t heed him, don’t delay his punishment, don’t show him reverence.

Parallel to Mitzvah 44 (Not to falsely prophesy in Hashem’s Name):

  • Mitzvah 44 forbids false prophecy.
  • Mitzvah 45 ensures no fear prevents justice.
  • Talmud (Sanhedrin 89a) ties them together: the prophet who presumes falsely must die, and Israel must not shrink from that duty.

Applying this Mitzvah Today

Courage in Safeguarding Torah Integrity

  • Rambam (Sefer HaMitzvot, Lo Ta’aseh 15) teaches that fear of public backlash must not prevent enforcement against false prophecy. In today’s context, this mitzvah instructs us not to shrink from opposing those who misrepresent Torah — even if they are charismatic, influential, or supported by powerful groups.

Resisting Charismatic Manipulation

  • Talmud (Sanhedrin 89a) describes the danger of the false prophet who deceives with signs or persuasive rhetoric. In the modern age, this can parallel cult leaders, self-proclaimed “messiahs,” or even those using Torah to justify unethical behaviors. The mitzvah directs us to confront, rather than avoid, these dangerous distortions.

Community Leadership Responsibility

  • Sefer HaChinuch (Mitzvah 516) highlights that communal leaders must act decisively to preserve Torah integrity. Today, rabbis, batei din, and communal bodies are obligated to publicly denounce fraudulent religious claims, ensuring communities are not misled.

Moral Courage Over Social Pressure

  • Ramban (Deut. 18:22) emphasizes that fear of public opinion must not override fidelity to Hashem. In the digital age, where false religious claims can spread rapidly online, this mitzvah demands individuals and leaders speak truth even when unpopular, embodying moral courage in the face of ridicule or cancelation.

Guarding Against Religious Exploitation

  • Midrash (Sifrei Devarim 172) explains that Hashem commanded firmness against false prophets because they erode the foundation of Torah. Applied today, this requires vigilance against religious exploitation — when Torah language is misused to justify greed, abuse, or power-seeking.

Notes on this Mitzvah's Fundamentals

Prophecy – נְבוּאָה

  • Rambam (Yesodei HaTorah 10:4) states that prophecy’s sanctity depends on rejecting false prophets without hesitation. Talmud (Sanhedrin 89a) emphasizes that once tested false, prophecy demands his death. Sefer HaChinuch (518) stresses that not fearing them preserves the prophetic tradition’s sanctity.

Faith – אֱמוּנָה

  • Rashi (Deut. 18:22) teaches that faith is tested when people fear a prophet’s stature or following. Ramban explains that Torah demands loyalty to Hashem over fear of man. Midrash (Sifrei 178) frames courage here as an act of emunah, clinging to Hashem’s truth above all.

Reverence – יִרְאַת שָׁמַיִם

  • Rambam notes that true yirat Shamayim rejects fear of flesh and blood. Sefer HaChinuch says awe of Hashem must eclipse awe of man. Talmud (Sanhedrin 90a) affirms that courage to punish false prophets is itself reverence for Heaven.

Justice – צֶדֶק

  • Ramban insists justice demands that false prophets be punished swiftly. Talmud (Sanhedrin 89a) codifies their execution as Torah’s requirement. Sefer HaChinuch stresses that sparing them out of fear perverts justice.

Community – קְהִלָּה

  • Rambam explains that communal courage is needed so Israel remains faithful. Rashi notes that a community’s hesitation corrupts its strength. Midrash (Sifrei 178) highlights that courage in removing false prophets preserves communal unity.

Core Beliefs – יְסוֹדוֹת הָאֱמוּנָה

  • Rambam (Sefer HaMitzvot, Negative Commandment 25) lists this mitzvah as central to preserving ikarei emunah. Ramban warns that allowing a false prophet to live implies Torah’s word is not final. Sefer HaChinuch stresses this mitzvah as a foundation of Torah permanence.

Bein Adam L’Makom – בֵּין אָדָם לְמָקוֹם

  • Rambam explains this mitzvah is directly covenantal: loyalty to Hashem requires rejecting fear of men. Rashi interprets “do not fear him” as clinging only to Hashem. Midrash (Sifrei 178) sees it as deveikut in its purest form.
