'Virgin' in the Bible

Therefore, the Lord Himself will give you a sign: The virgin will conceive, have a son, and name him Immanuel.

“Go down and sit in the dust,Virgin Daughter Babylon.Sit on the ground without a throne,Daughter Chaldea!For you will no longer be called pampered and spoiled.

For as a young man marries a young woman,so your sons will marry you;and as a groom rejoices over his bride,so your God will rejoice over you.
