Acts 19:11-20 - Would-Be Exorcists
11 And God performed special miracles through the hands of Paul, 12 such as sick people, who were given hand towels or [leather] aprons that had touched Paul's body, being healed from diseases and delivered from evil spirits.

When they calculated the cost [of the books] it came to fifty thousand pieces of silver. [Note: The actual amount was approximately years of a farm laborer's pay, or more than 20 So, the message of the Lord spread widely and had a great influence [over people].
