Should hell give some tell, then some tones would I sound; Per "hells "signal it "sings". May it also be interpreted as come alive or be put to use. assuming that by this "hell(s)" is what bring it into action and compels it to rest
Should night turn to light, then to holes be I bound. By day time it's confined or conformed to holes
When hell will sound a bell, then to bones shall I turn, And also by "hells" "bells" it turns to bone
And I shall be as ones should an urn be burn. This last line is what confuses me
I keep thinking of some instrument or tool of some sort. "Hell" makes me picture a furnace or morgue.
