'Soul' in the Bible

Say, O love of my soul, where you give food to your flock, and where you make them take their rest in the heat of the day; why have I to be as one wandering by the flocks of your friends?

By night on my bed I was looking for him who is the love of my soul: I was looking for him, but I did not see him.

I will get up now and go about the town, in the streets and in the wide ways I will go after him who is the love of my soul: I went after him, but I did not see him.

I was but a little way from them, when I came face to face with him who is the love of my soul. I took him by the hands, and did not let him go, till I had taken him into my mother's house, and into the room of her who gave me birth.

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.
