Moth - Vine's Expository Dictionary of New Testament Words
Moth[ 1,,G4597, ses ]
denotes a clothes moth," Matthew 6:19-Matthew 6:20; Luke 12:33. In Job 4:19 "crushed before the moth" alludes apparently to the fact that woolen materials, riddled by the larvae of "moths," become so fragile that a touch demolishes them. In Job 27:18 "He buildeth his house as a moth" alludes to the frail covering which a larval "moth" constructs out of the material which it consumes. The rendering "spider" (marg.) seems an attempt to explain a difficulty.
