The Hebrew word rephesh, represented by H7516, is defined as mud (as roiled); mire. It is a highly specific term, appearing just 1 time in 1 unique verse in the entire Bible, which gives its single usage significant weight and focus.
The sole appearance of H7516 is in Isaiah 57:20, where it is used in a powerful simile to describe the nature of the ungodly. The verse states, "But the wicked are like the troubled sea, when it cannot rest, whose waters cast up mire and dirt." Here, mire is not literal mud but a metaphor for the foulness and impurity that is continuously produced by the restless turmoil of the wicked. It is the external evidence of an internal state that is unable to find peace or stillness.
Several related words from its context in Isaiah 57:20 help clarify the meaning of H7516:
- H7563 râshâʻ (wicked): Defined as a "morally wrong; concretely, an (actively) bad person," this word identifies the source of the turmoil that produces the mire. The wicked are the subject of the metaphor Isaiah 57:20.
- H1644 gârash (cast up / troubled): This verb means "to drive out from a possession" and is translated as both "troubled" and "cast up" in the verse. It implies that the mire is not stagnant but is actively and forcefully expelled, similar to how God would drive out enemies Exodus 6:1.
- H2916 ṭîyṭ (dirt): Meaning "mud or clay; figuratively, calamity," this word appears alongside mire. It is often associated with being brought low or trapped in calamitous situations, such as in a "horrible pit" or "miry clay" Psalms 40:2.
- H8252 shâqaṭ (rest): Meaning "to repose" or "be still," this is the state the wicked sea cannot achieve Isaiah 57:20. This lack of rest is contrasted with the "quietness" that is the effect of righteousness Isaiah 32:17.
The theological significance of H7516 is concentrated in its single, potent image:
- The Fruit of Wickedness: The mire is presented as the direct byproduct of the wicked. It is what they "cast up," making it a symbol for the corrupting influence and foulness that emanates from a life of ungodliness Isaiah 57:20.
- A State of Perpetual Turmoil: The word is intrinsically linked to the image of a sea that "cannot rest" Isaiah 57:20. This contrasts sharply with the peace that comes from God, highlighting that a life apart from Him is one of constant, unproductive agitation.
- Visible Impurity: Because the mire is "cast up," it represents an inner corruption that cannot be contained. It becomes a visible and unavoidable consequence of the wicked person's nature, an external defilement that springs from internal unrest.
In summary, H7516 rephesh transcends its simple definition of mire. Within its single biblical context, it serves as a powerful metaphor for the filth and impurity that is the inevitable result of the wicked person's restless existence. It illustrates that a life without the peace of God is not merely empty but is in a state of constant turmoil that actively produces and expels corruption.
