Core Meaning & Semantic Range

The Hebrew word ʼûwr, represented by H217, denotes fire or light. Its base definition describes it as a flame. It appears 6 times across 6 unique verses. While it can refer to a literal fire, it is often used in prophetic contexts to symbolize divine power, judgment, or the light of human origin.

Biblical Occurrences & Contextual Analysis

The uses of H217 illustrate a duality between comfort and judgment. In Isaiah 44:16, it is the satisfying fire a person warms himself by, saying, "I have seen the fire". Conversely, in Ezekiel 5:2, it is a destructive fire for burning a third part of the city in a sign of judgment. The LORD's own presence is described as a fire H217 in Zion and a furnace in Jerusalem, signifying his power Isaiah 31:9. In another instance of judgment, Babylon will be destroyed so completely that there will not be a fire H217 to sit before Isaiah 47:14. The term can also refer to the "fires" where people are called to glorify the LORD Isaiah 24:15.

Related Words & Concepts

Several related words provide a broader context for heat and flame:

  • H784 ʼêsh (fire): A primitive word for fire used literally or figuratively. It appears alongside H217 in contexts of both judgment and human activity Isaiah 50:11.
  • H3852 lehâbâh (flame): This word for flame is used to describe the intensity of a destructive fire from which there is no escape Isaiah 47:14.
  • H8574 tannûwr (furnace): This term is paired directly with the LORD's fire H217 to describe his presence in Jerusalem, linking divine power to an intense source of heat Isaiah 31:9.
  • H2552 châmam (to be hot): This root word for being warm is used in the context of warming oneself by a fire, but its absence is noted in a scene of judgment where no coal will be left to warm at Isaiah 47:14.

Theological Significance

The theological weight of H217 is significant, particularly in the writings of Isaiah.

  • Symbol of Divine Presence: The LORD's presence in Zion is explicitly identified as a fire H217, indicating His powerful and potentially dangerous immanence among His people Isaiah 31:9.
  • Instrument of Judgment: The word is used in prophetic acts to represent God's judgment. Ezekiel is commanded to burn a third of the hair representing Jerusalem with fire H217 Ezekiel 5:2. Similarly, the complete destruction of Babylon is shown by the lack of even a comforting fire H217 Isaiah 47:14.
  • Misguided Human Effort: Isaiah 50:11 uses the light H217 of a man-made fire as a metaphor for self-reliance. To walk in this light is to "lie down in sorrow," illustrating the futility of human schemes apart from God.

Summary

In summary, H217 provides a specific nuance for fire and light in the Old Testament. While appearing only a few times, it effectively conveys a range of meanings, from the simple comfort of a warming fire Isaiah 44:16 to the awesome power of God's presence and judgment Isaiah 31:9. It is particularly potent as a symbol distinguishing between the insufficient light of human origin and the authoritative, all-consuming fire of the LORD.
