'Soul' in the Bible

Tell me, O thou whom my soul loveth, where thou feedest, where thou makest thy flock to rest at noon: for why should I be as one that turneth aside by the flocks of thy companions?

By night on my bed I sought him whom my soul loveth: I sought him, but I found him not.

I will rise now, and go about the city in the streets, and in the broad ways I will seek him whom my soul loveth: I sought him, but I found him not.

The watchmen that go about the city found me: to whom I said, Saw ye him whom my soul loveth?

It was but a little that I passed from them, but I found him whom my soul loveth: I held him, and would not let him go, until I had brought him into my mother's house, and into the chamber of her that conceived me.

I opened to my beloved; but my beloved had withdrawn himself, and was gone: my soul failed when he spake: I sought him, but I could not find him; I called him, but he gave me no answer.

Or ever I was aware, my soul made me like the chariots of Amminadib.
