Acts 16

When Paul encountered a demon-possessed woman on the way to the river to pray, he was so annoyed by her disruption that he turned and said, “In the name of Jesus Christ, I COMMAND YOU to come out of her.”  The spirit immediately left her.

When dealing with demon spirits, it’s wise to use scriptural wording. If it works for Paul, (and it’s recorded in scripture) don’t try to improve with your own methodology.
