'Mighty' in the Bible

How hath she sat alone, The city abounding with people! She hath been as a widow, The mighty among nations! Princes among provinces, She hath become tributary!

The Lord hath trodden under foot all my mighty men in the midst of me: he hath called an assembly against me to crush my young men: the Lord hath trodden the virgin, the daughter of Judah, as in a winepress.

For these I am weeping, My eye, my eye, is running down with waters, For, far from me hath been a comforter, Refreshing my soul, My sons have been desolate, For mighty hath been an enemy.
