'Back' in the Bible

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.

Come back, come back, O Shulammite; come back, come back, so that our eyes may see you. What will you see in the Shulammite? A sword-dance.
