'Worm' in the Bible

Fear not, thou worm Jacob, ye men of Israel; I will help thee, saith Jehovah, and thy Redeemer, the Holy One of Israel.

For the moth shall eat them up like a garment, and the worm shall eat them like wool; but my righteousness shall be for ever, and my salvation from generation to generation.

And they shall go forth, and look upon the carcases of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorrence unto all flesh.
