a. Some of the itinerant Jewish exorcists: At that time, there were Jewish exorcists who practiced their trade with a lot of superstition and ceremony. Here, a group of itinerant Jewish exorcists tried to imitate what they though was Paul’s formula for success.

b. We exorcise you by the Jesus whom Paul preaches: The Jewish exorcists failed because they had no personal relationship with Jesus. They only knew that Jesus was the God of Paul, not their own God.

ii. We could say that the sons of Sceva did not have the right to use the name of Jesus, because they had no real personal connection to Him

Names were very significant in biblical times; even prophetic, like in this case. The baby inside of Mary's womb would someday die on the cross to save mankind from their sins. He would be the personification of what this name meant.

There are many times in the bible where his name is written as Jesus Christ. One might think when we say Jesus Christ that Christ is his last name but that's not the case. The proper phrase would be Jesus who is the Christ. That's why you will also find it written as Christ Jesus.

Christ is the Greek translation of the Hebrew word Messiah or Anointed One. The one the Jews had been waiting centuries for was here. Jesus is the one who was to come into the world. He is the Messiah, the Anointed One, the Redeemer, the great deliverer, the Savior. This is the name of Jesus.
