'Mighty' in the Bible

And his power will grow, but not by his [own] power, and he will cause fearful destruction, and he will succeed and {he will act}, and he will destroy [the] mighty and [the] people of [the] holy ones.

And a mighty king will arise, and he will rule [with] great dominion, and he will do {as he pleases}.

And {before him} {mighty military forces} will be utterly swept away, and they will be broken, and also [the] leader of [the] covenant.
