"The soul that sinneth, it shall die" Ezekiel
So, are you agreeing that there is such a thing as a soul?
Hebrew 'nephesh' seems to be used to mean simply the whole person, as 'soul' is sometimes used in English.
"And man became a living soul" - Genesis 2, if I'm not mistaken.
I'm not denying that these concepts changed over time in the scriptures - particularly during the inter-testamental years. By the time we get to Christianity, lots of other stuff has got mixed into the pudding.
