'Soul' in the Bible

For the word of God is living, and active, and sharper than any two-edged sword, and piercing even to the dividing of soul and spirit, of both joints and marrow, and quick to discern the thoughts and intents of the heart.

which we have as an anchor of the soul, a hope both sure and stedfast and entering into that which is within the veil;

But my righteous one shall live by faith: And if he shrink back, my soul hath no pleasure in him.

But we are not of them that shrink back unto perdition; but of them that have faith unto the saving of the soul.
