Acts 19:5-6

⁵His auditis, baptizati sunt in nomine Domini Iesu;

⁶et cum imposuisset illis manus Paulus, venit Spiritus Sanctus super eos, et loquebantur linguis et prophetabant.

Acts 19 marks a pivotal turning point in Paul's ministry: the extended stay in Ephesus. This chapter is a dense narrative of gospel advance and cultural collision. Paul finds a group of disciples who only knew John's baptism, corrects their understanding, and the Holy Spirit falls.
