Word Study

In depth

A plain-language study of kâhâh — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Hebrew word kâhâh, represented by H3543, is a primitive root used to describe weakness. It appears 8 times across 7 unique verses. Its meaning encompasses a range of concepts including the physical growing dull of the eyes, the figurative despondence of the spirit, and the failure to act or rebuke. It can mean to be dim, to darken, to fail, to faint, or to restrain.

Biblical Occurrences & Contextual Analysis

In biblical usage, H3543 often describes the physical effects of old age or sorrow. When Isaac was old, his "eyes were dim" Genesis 27:1, and Job states that his "eye also is dim by reason of sorrow" Job 17:7. In contrast, Moses's vitality at his death is highlighted by the fact that his "eye was not dim" Deuteronomy 34:7. The word also portrays emotional or spiritual collapse, as in the prophecy that "every spirit shall faint" Ezekiel 21:7. It can signify a failure of duty, as when Eli did not restrain his vile sons 1 Samuel 3:13. In a prophecy against a false leader, it is used twice to state his eye "shall be utterly darkened" Zechariah 11:17.

Related Words & Concepts

Several related words help clarify the concept of weakness and failure:

  • H7533 râtsats (discourage): This word is used in parallel with H3543 in Isaiah 42:4, stating that the prophesied figure "shall not fail nor be discouraged," contrasting divine resolve with human frailty.
  • H7503 râphâh (fail, be feeble, weak): This term appears alongside H3543 in Ezekiel's prophecy of judgment, where hands "shall be feeble" as every spirit "shall faint" Ezekiel 21:7.
  • H5869 ʻayin (eye): This is the part of the body most often associated with H3543. The dimming of the eye serves as a physical sign of age Genesis 27:1, sorrow Job 17:7, or divine judgment Zechariah 11:17.

Theological Significance

The theological significance of H3543 is seen in its application to both human limitation and divine power.

  • Physical and Spiritual Frailty: The word connects the physical decline of eyesight in figures like Isaac and Job to the spiritual despair prophesied in Ezekiel, illustrating a holistic view of human weakness (Genesis 27:1, Job 17:7, Ezekiel 21:7).
  • Moral Failure: In the case of Eli, the word shifts from a passive state to an active failure of responsibility. His failure to restrain his sons demonstrates a lack of moral fortitude that brings judgment upon his house 1 Samuel 3:13.
  • Contrast between Judgment and Steadfastness: H3543 is used to describe the result of judgment upon the "idol shepherd," whose eye will be "utterly darkened" Zechariah 11:17. Conversely, the figure in Isaiah "shall not fail," presenting a powerful contrast between human collapse and divine perseverance Isaiah 42:4.

Summary

In summary, H3543 is a multifaceted term that conveys concepts of weakness, dimness, and failure. It is used literally to describe the loss of eyesight and figuratively for a fainting spirit or a moral lapse. Through its use, scripture contrasts the natural decay and frailty of humanity with the unique, sustained vigor of figures like Moses and the unwavering strength of the one who, unlike others, will not fail or be discouraged.
