עָשׁ
a moth
Definition
The Hebrew word עָשׁ (ʻâsh) refers specifically to a moth, a small insect known for consuming and destroying cloth and other organic materials. In the Bible, it is used both literally, as in Job 27:18 where a moth-eaten house symbolizes ruin, and metaphorically to represent fragility, impermanence, and destructive decay. For instance, in Job 4:19, humans are described as dwellings that moths can destroy, highlighting human frailty. In prophetic passages like Isaiah 50:9 and 51:8, the moth serves as a metaphor for the eventual, certain destruction of the wicked, which will consume them as a moth consumes fabric.
Biblical Usage
This noun appears 12 times, primarily in poetic and wisdom literature (Job, Psalms) and prophetic books (Isaiah, Daniel). Its usage consistently emphasizes destruction, fragility, and transience. In Job, it illustrates human mortality and the crumbling of wealth (Job 13:28, 27:18). The Psalms use it to describe the fleeting nature of life and beauty (Psalm 39:11). In Isaiah, it symbolizes the certain but gradual destruction of enemies (Isaiah 50:9, 51:8). In Daniel 4:15, 25 (Aramaic section), it appears in Nebuchadnezzar's dream, where the phrase 'let his portion be with the beasts of the field' uses 'moth' in a simile for his humbled state.
Etymology
The noun עָשׁ (ʻâsh) is derived from the root עשׁשׁ (ʻâshash, H6244), which means 'to fall away, disappear, or waste away.' This root connection directly informs the word's meaning, linking the moth to the concept of gradual consumption and decay. Cognates exist in other Semitic languages, like Ugaritic and Arabic, with similar meanings related to moths or insects that cause destruction.
Semantic Range
The moth is a potent biblical symbol for the transient nature of earthly life, human frailty, and the inevitable decay of material wealth and human glory. It underscores the wisdom theme that trust should be placed in the eternal God rather than in perishable things (cf. Matthew 6:19-20). Understanding this Hebrew metaphor enriches reading by highlighting the contrast between what is temporary and what is everlasting, a key concept in both wisdom and prophetic literature.
In ancient Near Eastern culture, moths were a common and destructive household pest, ruining valuable wool and linen garments, which represented significant wealth and status. This made the moth a powerful and immediate symbol of loss and impermanence for the original audience. The metaphor relied on the experience of watching prized possessions slowly be consumed from within, unseen until the damage was evident.
עַיִשׁ (ʻayish, H5906) — A different word sometimes translated 'moth' or 'constellation' (like the Bear); context determines meaning, but it shares a phonetic similarity.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
