'Worm' in the Bible

Brought down to Sheol hath been thine excellency, The noise of thy psaltery, Under thee spread out hath been the worm, Yea, covering thee is the worm.

Fear not, O worm Jacob, ye men of Israel, I helped thee, an affirmation of Jehovah, Even thy redeemer, the Holy One of Israel.

For as a garment eat them doth a moth, And as wool eat them doth a worm, And My righteousness is to the age, And My salvation to all generations.

And they have gone forth, And looked on the carcases of the men Who are transgressing against me, For their worm dieth not, And their fire is not quenched, And they have been an abhorrence to all flesh!
