I think it was the Targum of Jonathan, but I can't remember for certain, one of them, anyway, on this place,You seem to know what these words mean in modern Western culture but do you know what they mean in Hebrew culture?
Isaiah 66:24 KJV
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 abhorring unto all flesh.
It expressed their understanding that this "worm" is "what remains of a man whom God has destroyed".
I remember when I read that, I immediately thought of Psalm 22,
Psalms 22:6 KJV
But I am a worm, and no man; a reproach of men, and despised of the people.
He took our place.
Much love!
