'Dove' in the Bible

My dove, in the hidden places of the rocks, in the secret places of the cliffs, show me your form, and let me hear your voice. For your voice is pleasant, and your shape is lovely.

I was asleep, but my heart was awake. There's a sound! My beloved is knocking. "Open up for me, my sister, my darling, my dove, my perfect one. For my head is drenched with dew, my hair with the dampness of the night."

but my dove, my perfect one, is unique. She's unique to her mother, she's pure to the one who gave birth to her. Young women see her and call her blessed, queens and mistresses praise her.
