Really? So He commended His dead spirit to the Father? :noway:
The human spirit joins with the brain to create a person's mind.
"Now may the God of peace Himself sanctify you completely and may your whole spirit, soul, and body be preserved" (1 Thessalonians 5:23)
The spirit is pneuma, soul is psuche from which we get psyche, body is soma.
When the spirit separates from the body the soul is dead.
