The baptism of John, whence was it? (Acts 19)

Acts chapter 19 opens with a few more people in Ephesus who are only familiar with the work of John the Baptist. Paul meets these men and asks them if they've received the Holy Ghost, and they essentially respond with, "Holy Ghost? Never heard of it!" Paul tells them about Jesus, and baptizes them again. It's an interesting doctrinal point here that Paul makes, saying the baptism of John was a baptism of repentance, which might make one wonder what the baptism of Jesus is about, because it sounds like Paul is contrasting here. The men receive the Holy Ghost and speak in tongues, prophesying. (Here's another instance of the Holy Ghost being given for the SAB.) After speaking in the synagogue for three months, the non-believing Jews start slandering Paul, so he leaves the synagogue and relocates to "the school of one Tyrannus" which the SAB notes as the only school in the entire Bible; while this may be technically true (that is, it's the only mention of "school") I think the idea of education is present throughout the Bible, and on the flipside, it's not really clear what kind of "school" this is. Anyway, Paul is in Ephesus for two years, and apparently his teaching of the gospel spreads throughout Asia (note that "Asia" in the Bible is referring to what we would call "Asia Minor" today).

There is mentioned some actually rather strange miracles here. It seems that Paul was working in Ephesus, and people would take his sweat rags and aprons and touch sick people with them, causing them to be cured. The Bible doesn't explain why this is effective, and yeah, I can see the "Absurdity" tag here. In a related story, some professional exorcists who are non-Christian Jews try to cast out a demon by saying, "We adjure you by Jesus whom Paul preacheth." The demon apparently finds this amusing saying he knows Jesus and Paul (with a different Greek word for "know" in each case, the NIV rendering the response, "Jesus I know, and Paul I know about, but who are you?") but doesn't know who the exorcists are, and he beats them up and strips them naked. Once again, the absurdity of this story is pretty obvious, although to those contemporary to it happening, it was apparently scary, and a bunch of people are essentially spooked into the kingdom of heaven.

Then there is noted a book burning. The SAB should really include this passage on their Is magic OK? page, because it's implied here that these are something like spellbooks. Paul is apparently thinking about traveling back to Jerusalem and then to Rome, but for now he sends Timothy and Erastus to Macedonia. In Ephesus, a silversmith named Demetrius gathers together craftsmen in the city who make money crafting (I assume) idols of the goddess Diana, and points out that the idol making craft is losing money from all these people turning to Christianity. They stir up a sort of rally for Diana, which turns into a would-be lynch mob for some Christians. The town clerk gets them to calm down and implores them to not do anything rash and illegal that they will regret, and the crowd disperses.
