In Hebrew the original word for Soul is ne′phesh and in Greek it is psy‧khe′
Throughout the Old and New testament it describes the living person, an animal, or the life that a person or an animal enjoys.
H. M. Orlinsky of Hebrew Union College, made this comment about the word soul: "The Bible does not say we have a soul. ‘Nefesh’ is the person himself, his need for food, the very blood in his veins, his being." The New York Times, October 12, 1962.
The New Catholic Encyclopedia 1967, Vol. XIII, p. 467 says: “Nepes [ne′phesh] is a term of far greater extension than our ‘soul,’ signifying life and its various vital manifestations: breathing, blood, desire. The soul in the O[ld] T[estament] means not a part of man, but the whole man—man as a living being. Similarly, in the N[ew] T[estament] it signifies human life: the life of an individual, conscious subject”
So the soul is the living breathing person. As Issac Newton put it, "you dont have a soul, you are a soul"
