Temple – בֵּית הַמִּקְדָּשׁ

A perpetual fire must be lit upon the altar, renewed each morning by the Kohanim.

This mitzvah commands the Kohanim to light and maintain a continual fire on the Mizbeach. The fire consumed the daily Tamid offerings and other korbanot, symbolizing the eternal relationship between Israel and Hashem. The Kohanim were required to place wood on the altar each morning to ensure the flame never went out.

The Talmud (Yoma 45b) explains that although fire descended from Heaven, it was a mitzvah for the Kohanim to add human fire, teaching partnership between Divine power and human effort. Rambam codifies that the altar must never be without fire, as it represents the constant presence of Hashem’s service. Sefer HaChinuch explains that the perpetual flame serves as a physical reminder of unbroken devotion and awe. Midrash Tanchuma teaches that the fire’s constancy corresponds to the eternal covenant between Hashem and Israel.

Commentary & Classical Explanation:

  • Rambam (Hilchot Temidin uMusafin 2:1): Codifies that the altar’s fire must never be extinguished, with wood added daily.
  • Sefer HaChinuch (Mitzvah 132): Explains that the fire symbolizes unceasing devotion, keeping Israel mindful of Hashem’s presence.
  • Talmud (Yoma 45b): Notes that Heavenly fire coexisted with human fire, teaching partnership in service.
  • Midrash Tanchuma (Tzav 14): Connects the perpetual fire with the eternal covenant between Hashem and Israel.
  • Rashi (Lev. 6:5): Comments that “it shall not be extinguished” means not even for a moment, emphasizing constancy.

Notes on this Mitzvah's Fundamentals

Holiness – קְדֻשָּׁה

  • Sefer HaChinuch (132) explains that the perpetual fire instills holiness by keeping Israel aware that Hashem’s service never ceases. The constancy of the flame elevates the altar from a physical structure to a symbol of sanctity itself. Ramban (Lev. 6:5) adds that holiness rests where fire burns continually for Hashem, marking His chosen place.

Temple – בֵּית הַמִּקְדָּשׁ

  • Rambam (Temidin 2:1) teaches that the continual fire defined the Temple’s uniqueness, for no other place could host Hashem’s eternal flame. Midrash Rabbah (Vayikra 7:3) teaches that the Temple fire paralleled the fire of Sinai, reminding Israel that the Mikdash perpetuates revelation daily.

Mizbeach – מִזְבֵּחַ

  • Talmud (Yoma 45b) describes that the fire descended from Heaven in the form of a crouching lion, yet the Kohanim had to add human fire. This partnership demonstrated that the Mizbeach connected Heaven and earth, human action and Divine presence.

Sacrifices – קָרְבָּנוֹת

  • Rashi (Lev. 6:5) explains that the flame consumed not only the Tamid but also fats and limbs from other offerings, completing the sacrificial service. Sifri (Tzav §19) adds that without fire, korbanot lose their essence, since the burning symbolizes ascent to Hashem.

Faith – אֱמוּנָה

  • Midrash Tanchuma (Tzav 14) interprets the perpetual flame as a testimony that Hashem’s covenant with Israel is eternal. Just as the fire never ceased, His providence never ceased. Rambam (Moreh Nevuchim 3:46) writes that this constancy cultivated faith, teaching Israel to trust in Divine permanence.

Reverence – יִרְאַת שָׁמַיִם

  • Rambam (Temidin 2:2) states that extinguishing the flame, even momentarily, incurs severe punishment, cultivating fear and diligence. Talmud (Menachot 110a) explains that the fire represented Hashem’s glory; to treat it casually was to diminish awe of Heaven.

Covenant – בְּרִית

  • Midrash Tanchuma (Tzav 14) compares the perpetual fire to the covenant of day and night (Jeremiah 33:25). Just as day and night never fail, so too Israel’s covenant never lapses — embodied by the altar’s fire. Ramban (Lev. 6:5) affirms that this mitzvah is a visible sign of Israel’s eternal bond with Hashem.

Bein Adam L’Makom – בֵּין אָדָם לְמָקוֹם

  • Rambam (Sefer HaMitzvot, Aseh 29) codifies that this mitzvah is wholly between man and Hashem, reflecting Israel’s obligation to continually dedicate service to Him. The flame shows that worship is not seasonal but constant, binding Israel directly to the Divine.
