The 'soul' fundamentally referring to all the constituents of a person can sometimes refer to the spirit as well. However, normally there is a difference in meaning between 'soul' and 'spirit' as used in the Bible; soul and spirit can be 'divided asunder' (Heb. 4:12).
Ingawa hivyo, kwa kawaida kuna tofauti katika maana kati ya'nafsi’ na'Roho’ kama yalivyotumika katika Biblia; nafsi na Roho zaweza'kugawanyika’ (Ebra. 4: 12).
