Here is the rewritten verse in simple modern English: You will be sent into darkness, chains, and burning fire where there is severe punishment. This great punishment will happen to all people for all time. You are in trouble because you will never have peace.
And into darkness and chains and a burning flame where there is grievous judgement shall your spirits enter; And the great judgement shall be for all the generations of the world. Woe to you, for ye shall have no peace.
