By the Hebrew word we are certainly to understand some species of clothes-moth (tinea ). Reference to the destructive habits of the clothes-moth is made in ( Job 4:19 ; 13:28 ; Psalms 39:11 ) etc. (The moth is a well-known insect which in its caterpillar state is very destructive to woollen clothing, furs, etc. The egg of the moth, being deposited on the fur or cloth, produces a very small shining insect, which immediately forms a house for itself by cuttings from the cloth. It east away the nap, and finally ruins the fabric. There are more than 1500 species of moths. --McClintock and Strongs Cyclopedia.)
