EDIT to respond to OPs comments below and above: There is a need to further clarify the claim that Christ is one person (not two), so as to understand in what sense Jesus (as God) died, if his spirit/soul never died; only his physical body did, yet how could his body never have a life of its own separate from the human spirit? This is why fully understanding the nephesh of man is vital. I will quote a few points from the book below, but as it takes 123 pages to explain Jesus as the Son of Man, I can only give a tit-bit.
"Nephesh, itself, is translated: soul, life, heart, creature, mind, pleasure, will or desire; and many more. Clearly it conveys a very broad concept of that which is within. Not of different nature from that which encloses it, as nepheth shows; but that which is, potentially, a different possession. Thinking of Ezekiel 18:4, I would say that men, such as progenitors, may have some claim to that of us which is created and material but there is that within us which is also created but that is the possession of God himself and to him it shall, most definitely return...
Finally, nacham is the releasing of oneself. One's real self is released in a context were one had been, heretofore, unable to express one's true self and one's real purpose and one's true disposition ["his glory veiled"]. Due to some change of circumstance, one is no longer restricted and one's real self is released. Coming forth...
In fact, the Lord had been able to nacham consequent upon the transgression of Saul. Released to do that which was in his own heart (for David was a man after God's heart) the Lord would remain constant to that which he, ever, was, within himself. Saul's outward transgression revealed his unseen state of heart and released God to do what was in his own heart - by means of the man, David, whose heart was as the heart of God.
For the constancy of the Lord is a consistency with his own self. He does nothing that is in conflict with what he is, by nature. Here is his righteousness; a matter of his nature. I am that I am. His living is consistent with that he is. Righteousness may require that he restrain that which is his ultimate purpose, until circumstance permit it. Then he shall do what is truly consistent to himself. He shall nacham. But he shall not release himself from just obligation, as men do...
In like manner waits the Son of man now, until he is given authority. Immediately he receives it, he shall dash the nations in pieces as with a rod of iron shattering earthenware into shivers. As God bore long in this age with men in the antediluvian age, until, in Noah, he could nacham; so also the Father bears long in this age until all things be accomplished and then shall the Son of man do all that is in the heart of God, to the fulfilment of all things...
After death, the blood of Christ was poured out on earth; it redeemed many when it was shed; it justified many, out of the faith of the one who shed it; it was sprinkled in heaven, by him whose it was; it is drunk in faith, in spirit; the blood of Christ washes and the blood of Christ cleanses all who partake of it, by faith.
F) His Soul - Jesus speaks of his psuche on a number of occasions, but sometimes the AV gives 'life' and sometimes 'soul'... Of the last Adam [Christ] ...He is uncreated, a quickening spirit, zoe pneuma, 1 Corinthians 15:45, but without the italics of the AV which have no place on earth. This as to what he is, of everlasting. Come of woman, his living spirit is expressed through a psuche and of that psuche he speaks. There is no need, logically or etymologically, to say any more of that soul. It is a soul. To add another descriptive term to it (and I absolutely refuse to do so) implies that other kinds of souls exist, which they do not. A soul is a soul. That is what it is...
G] His Spirit - ...Luke 23:46. After saying, Father, into thy hands I will commit my spirit, voluntarily he expneuma." The Son - of man, Nigel Johnstone, pages 27, 30-31, 83 & 87, Belmont, 2014
Alas, it needs many more points from this book to properly answer the question. Having read all of it myself, I can only urge reading of it on-line at the link below, or order a free copy. But this subject is so complex, it just is not possible to do justice to this complex question without in-depth study. Studying all 123 pages here would greatly assist. https://belmontpublications.co.uk/wp-content/uploads/2021/05/10A-The-Son-of-man.pdf
