'Worm' in the Bible

“Do not fear, you worm Jacob, you men of Israel;I will help you,” declares the Lord, “and your Redeemer is the Holy One of Israel.

“For the moth will eat them like a garment,And the worm will eat them like wool.But My righteousness and justice [faithfully promised] will exist forever,And My salvation to all generations.”

“Then they will go forth and lookUpon the dead bodies of the [rebellious] menWho have transgressed against Me;For their worm (maggot) will not die,And their fire will not go out;And they will be an abhorrence to all mankind.”
