'Door' in the Bible

The Beloved about Her Lover: I was asleep, but my mind was dreaming. Listen! My lover is knocking at the door! The Lover to His Beloved: "Open for me, my sister, my darling, my dove, my flawless one! My head is drenched with dew, my hair with the dampness of the night."

The mandrakes send out their fragrance; over our door is every delicacy, both new and old, which I have stored up for you, my lover.

If she is a wall, we will build on her a battlement of silver; but if she is a door, we will barricade her with boards of cedar.
