'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 is able to discern the thoughts and intentions of the heart.

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

But the righteous will live by faith. If he shrinks back, my soul has no pleasure in him."

But we are not of those who shrink back to destruction, but of those who have faith to the saving of the soul.
