"For his sovereignty [is] [an] everlasting sovereignty, and his kingdom [continues] from generation to generation.

And he said, "Look, I am making known to you what will happen in the period of wrath, for [it refers] to [the] appointed time of [the] end.

"Then the king will do {as he pleases}, and he will exalt himself and will consider himself above any god, and he will speak horrendous things {against} [the] God of gods, yet he will succeed until [the period] of anger is finished, for [what] is determined will be done.
