Why did God call the people "Virgin Israel"? (Jeremiah 31:4)

Jeremiah 31:3 The Lord appeared to us in the past,[a] saying:

“I have loved you with an everlasting love;
    I have drawn you with unfailing kindness.
4 
I will build you up again,
    and you, Virgin Israel, will be rebuilt.
Again you will take up your timbrels
    and go out to dance with the joyful.
