'Mighty' in the Bible

“You, O king, were looking, and behold, [there was] a single great statue; this image, which was large and of unsurpassed splendor, stood before you, and its appearance was awesome and terrifying.

“How great are His signsAnd how mighty are His wonders!His kingdom is an everlasting kingdomAnd His dominion is from generation to generation.

“His power will be mighty, but not by his own power;And he will corrupt and destroy in an astonishing mannerAnd [he will] prosper and do exactly as he wills;He shall corrupt and destroy mighty men and the holy people.

“And now, O Lord our God, who brought Your people out of the land of Egypt with a mighty hand and who made for Yourself a name, as it is today—we have sinned, we have been wicked.

Then a mighty [warlike, threatening] king will arise who will rule with great authority and do as he pleases.

He will stir up his strength and courage against [his former Egyptian ally] the king of the South (Ptolemy VI) with a great army; so the king of the South will prepare an extremely great and powerful army to wage war, but he will not stand, for schemes will be devised against him.
