Like a moth— i.e. "As a moth consumes a garment." The Chaldee paraphrase has it, like a moth broken asunder; but the phrase is more properly applied to the moth's consuming other things, and not to the being itself consumed: thus Hosea 5:12. I will be to Ephraim as a moth; i.e. "I will consume him." and Isaiah 50:9. The moth shall eat them as a garment.

11 When thou with rebukes dost correct man for iniquity, thou makest his beauty to consume away like a moth: surely every man is vanity. Selah.
