Anointed
as it was used in this verse,
is from the Greek word, chrio, meaning,

To smear or rub with oil.
Thoughout the history of Israel, special people
entering into the service of the Lord (such as priests and kings), were first anointed with
oil, a Biblical  symbol of the Holy Spirit.
These people received a measure of power
from the Lord from this anointing.
But Jesus was anointed, not by a
priest, but by God, and not
with oil, but with the
"Holy Ghost, and
with power".





...God anointed Jesus of Nazareth
with the Holy Ghost and with power:
who went about doing  good,
and healing all that were
oppressed of the devil;
for God was with Him.

Acts 10:38
