'Soul' in the Bible

For the word of God is living and operative, and sharper than any two-edged sword, and penetrating to the division of soul and spirit, both of joints and marrow, and a discerner of the thoughts and intents of the heart.

which we have as anchor of the soul, both secure and firm, and entering into that within the veil,

But the just shall live by faith; and, if he draw back, my soul does not take pleasure in him.

But we are not drawers back to perdition, but of faith to saving the soul.
