'Virgin daughter' in the Bible

And He said, You shall rejoice no more, O crushed one, virgin daughter of Sidon. Arise, pass over to Chittim; also there you shall have no rest.

Come down, and sit on the dust, O virgin daughter of Babylon; sit on the ground. There is no throne for you, O daughter of the Chaldeans. For you shall no more be called tender and delicate.
