< Gen 1 "And YHWH God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man BECAME a living soul."
This text does not say that YHWH gave man a soul, but that man became a living soul.
Years ago, I did a study of the Bible's psych terms, like spirit, soul, heart, kidneys (reins), mind, heart (leb, lebab, kardia), flesh, thym- (thymos, epithymia). I need to rethink this actually, but the tentative conclusion I came to was the nephesh/psyche soul is a functional term, not metaphysical, which refers to the life or self. Consider that in the OT a dead body can be a dead soul. And there are 100 souls on a ship. This left me with the conclusion that there are only 2 metaphysical parts of man: body & spirit. But before concluding my work on this, I got diverted to a particular study of flesh (sarx) as a psych term & never really returned to the general subject in detail.
I am sure that trichotomy is not proven by the classic text in Heb 4:
"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. And there is no creature that is not manifest in his sight: but all things are naked and laid open before the eyes of him with whom we have to do."
Here Christ, the Word of God, has as it were X-ray vision to see what is inside soul, spirit, joints, & marrow. It is not "dividing from soul & spirit" as if you put a knife between the two, no more than slicing between joints & marrow (marrow is inside a bone, and text does not say "cut between marrow and bone"). But it is like a knife cutting open each of the 4 things. Only Christ can see inside the joints, the marrow (before X-rays were invented). Only He can see inside the soul & spirit. And at least to me this passage is not a technical presentation of metaphysical parts. To say that Christ can see inside the soul (the self) makes sense without claiming that psyche is a distinct metaphysical entity from spirit.
But, as I say, I really should look this over again.
