'Virgin' in the Bible

The Lord has set at nothing all my mighty men in the midst of me; He has called a solemn assembly against me to crush my young men: The Lord has trodden as in a winepress the virgin daughter of Judah.

What shall I testify to you? what shall I liken to you, daughter of Jerusalem? What shall I compare to you, that I may comfort you, virgin daughter of Zion? For your breach is great like the sea: who can heal you?
