'Soul' in the Bible

"Why does God give light to one who is in misery, and life to those whose soul is bitter,

"Therefore, I will not refrain my mouth; I will speak in the anguish of my spirit; I will complain in the bitterness of my soul.

"I am weary of my life; I will complain without restraint; I will speak in the bitterness of my soul.

And another man dies in bitterness of soul, never having tasted anything good.

"And now my soul pours itself out within me; days of suffering take hold of me.

Have I not wept for the unfortunate? Was not my soul grieved for the poor?

so that his life loathes food, and his soul rejects appetizing fare.
