'Mighty' in the Bible

And He hath judged between many peoples, And given a decision to mighty nations afar off, They have beaten their swords to ploughshares, And their spears to pruning-hooks, Nation lifteth not up sword unto nation, Nor do they learn war any more.

And I have set the halting for a remnant, And the far-off for a mighty nation, And reigned hath Jehovah over them in mount Zion, From henceforth, and unto the age.
