'Door' in the Bible

I am sleeping, but my heart is awake; it is the sound of my loved one at the door, saying, Be open to me, my sister, my love, my dove, my very beautiful one; my head is wet with dew, and my hair with the drops of the night.

My loved one put his hand on the door, and my heart was moved for him.

I got up to let my loved one in; and my hands were dropping with myrrh, and my fingers with liquid myrrh, on the lock of the door.

I made the door open to my loved one; but my loved one had taken himself away, and was gone, my soul was feeble when his back was turned on me; I went after him, but I did not come near him; I said his name, but he gave me no answer.

If she is a wall, we will make on her a strong base of silver; and if she is a door, we will let her be shut up with cedar-wood.
