'Successful' in the Bible

Because of rebellion, a host, together with the daily sacrifice, will be given over. The horn will throw truth to the ground and will be successful in whatever it does.

“Then the king will do whatever he wants. He will exalt and magnify himself above every god, and he will say outrageous things against the God of gods. He will be successful until the time of wrath is completed, because what has been decreed will be accomplished.
