'Worm' in the Bible

If I cry to corruption, 'You are my father,' and to the worm, 'My Mother,' or 'My sister,'

The womb forgets him, the worm feasts on him, no longer will he be remembered. Like a tree, wickedness will be broken down.

how much less a mortal man, who is but a maggot -- a son of man, who is only a worm!"
