'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.

“Then they will go forth and lookOn the corpses of the menWho have transgressed against Me.For their worm will not dieAnd their fire will not be quenched;And they will be an abhorrence to all mankind.”
