These scriptures are interesting in talking about soul , spirit & physical body
John 11:26 ......“everyone who lives and believes in me will never die.”
Matthew 10:28 where Jesus said, “[Do] not be afraid of those who can kill the body but cannot kill the soul (psuche); rather, be afraid of the one who can destroy both soul and body in Gehenna.

Eccl.12:7 [nwt]
Then the dust returns to the earth just as it happened to be and the spirit itself returns to the [true] God who gave it.
