Paul at Ephesus
19 1 It happened that, while Apollos was at Corinth, Paul, having passed through the upper country, came to Ephesus, and found certain disciples. 2 He said to them, “Did you receive the Holy Spirit when you believed?”
They said to him, “No, we haven’t even heard that there is a Holy Spirit.” 3 He said, “Into what then were you baptized?”
They said, “Into John’s baptism.” 4 Paul said, “John indeed baptized with the baptism of repentance, saying to the people that they should believe in the one who would come after him, that is, in Jesus.” 5 When they heard this, they were baptized in the name of the Lord Jesus. 6 When Paul had laid his hands on them, the Holy Spirit came on them, and they spoke with other languages and prophesied. 7 They were about twelve men in all.
8 He entered into the synagogue, and spoke boldly for a period of three months, reasoning and persuading about the things concerning the Kingdom of God. 9 But when some were hardened and disobedient, speaking evil of the Way before the multitude, he departed from them, and separated the disciples, reasoning daily in the school of Tyrannus. 10 This continued for two years, so that all those who lived in Asia heard the word of the Lord Jesus, both Jews and Greeks. 11 God worked special miracles by the hands of Paul, 12 so that even handkerchiefs or aprons were carried away from his body to the sick, and the evil spirits went out.
13 But some of the itinerant Jews, exorcists, took on themselves to invoke over those who had the evil spirits the name of the Lord Jesus, saying, “We adjure you by Jesus whom Paul preaches.” 14 There were seven sons of one Sceva, a Jewish chief priest, who did this. 15 The evil spirit answered, “Jesus I know, and Paul I know, but who are you?” 16 The man in whom the evil spirit was leaped on them, and overpowered them, and prevailed against them, so that they fled out of that house naked and wounded. 17 This became known to all, both Jews and Greeks, who lived at Ephesus. Fear fell on them all, and the name of the Lord Jesus was magnified. 18 Many also of those who had believed came, confessing, and declaring their deeds. 19 Many of those who practiced magical arts brought their books together and burned them in the sight of all. They counted the price of them, and found it to be fifty thousand pieces of silver.  20 So the word of the Lord was growing and becoming mighty.
19:19 The 50,000 pieces of silver here probably referred to 50,000 drachmas. If so, the value of the burned books was equivalent to about 160 man-years of wages for agricultural laborers
