'Virgin' in the Bible

Trodden down all my mighty ones hath the Lord in my midst, He proclaimed against me an appointed time, To destroy my young men, A wine-press hath the Lord trodden, To the virgin daughter of Judah.

What do I testify to thee, what do I liken to thee, O daughter of Jerusalem? What do I equal to thee, and I comfort thee, O virgin daughter of Zion? For great as a sea is thy breach, Who doth give healing to thee?
