'Worm' in the Bible

If I have said to corruption, 'You are my father;' to the worm, 'My mother,' and 'my sister;'

They lie down alike in the dust. The worm covers them.

The womb shall forget him. The worm shall feed sweetly on him. He shall be no more remembered. Unrighteousness shall be broken as a tree.

How much less man, who is a worm, the son of man, who is a worm!"
