'Powerful' in the Bible

The {astrologers} answered the king and said, "There is not a man on earth that is able to reveal the word of the king; {in fact}, no great and powerful king has [ever] asked a thing like this of any magician or conjurer or {astrologer}.

And after an alliance [is made] with him, he will act deceitfully, and he will rise and he will become powerful with few people [backing him].
