May the God of peace himself sanctify you completely. May your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.
See the use of the word in Matthew 22:37; Mark 12:30; Luke 10:27; Luke 12:20; Acts 20:10; Hebrews 4:12; Revelation 8:9, et al. In the Pythagorean and Platonic philosophy this was distinguished from the higher rational nature ὁ νοῦς, τὸ πνεῦμα ho nous, to pneuma as this last belonged to man alone. This “psyche” (ψυχὴ psuchē) “soul.” or life, it is commonly supposed, becomes extinct at death. It is so connected with the bodily organization, that when the tissues of the animal frame cease their functions, this ceases also. This was not, however, the opinion of the ancient Greeks. Homer uses the term to denote that which leaves the body with the breath, as escaping from the ἕρκος ὀδοντων herkos odontōn - “the fence or sept of thy teeth” - and as also passing out through a wound. - This ψυχή psuchē - “psyche” - continued to exist in Hades, and was supposed to have a definite form there, but could not be seized by the hands.
