'Mighty' in the Bible

For a [pagan and hostile] nation has invaded My land [like locusts],Mighty and without number;Its teeth are the teeth of a lion,And it has the fangs of a lioness.

A day of darkness and gloom,A day of clouds and of thick [dark] mist,Like the dawn spread over the mountains;There is a [pagan, hostile] people numerous and mighty,The like of which has never been beforeNor will be again afterwardEven for years of many generations.

Like the noise of chariotsThey leap on the tops of the mountains,Like the crackling of a flame of fire devouring the stubble,Like a mighty people set in battle formation.

They run like warriors;They climb the wall like soldiers.They each march [straight ahead] in line,And they do not deviate from their paths.

Proclaim this among the [pagan] nations:Prepare a war! Stir up the mighty men!Let all the men of war come near, let them come up!

Hurry and come, all you surrounding nations,And gather yourselves there;Bring down, O Lord, Your mighty ones (Your warriors).
