'Mighty' in the Bible

Pharaoh with his great army and mighty horde will not help him in battle, when siege ramps are erected and siege-walls are built to kill many people.

They will sing this lament over you: "'How you have perished -- you have vanished from the seas, O renowned city, once mighty in the sea, she and her inhabitants, who spread their terror!

By the swords of the mighty warriors I will cause your hordes to fall -- all of them are the most terrifying among the nations. They will devastate the pride of Egypt, and all its hordes will be destroyed.
