8 Paul then went straight to the meeting place. He had the run of the place for three months, doing his best to make the things of the kingdom of God real and convincing to them. 9 But then resistance began to form as some of them began spreading evil rumors through the congregation about the Christian way of life. So Paul left, taking the disciples with him, and set up shop in the school of Tyrannus, holding class there daily. 10 He did this for two years, giving everyone in the province of Asia, Jews as well as Greeks, ample opportunity to hear the Message of the Master. 11 God did powerful things through Paul, things quite out of the ordinary. 12 The word got around and people started taking pieces of clothing - handkerchiefs and scarves and the like - that had touched Paul's skin and then touching the sick with them. The touch did it - they were healed and whole.

Commentary on Acts 19:8-12
(Read Acts 19:8-12)
When arguments and persuasions only harden men in unbelief and blasphemy, we must separate ourselves and others from such unholy company. God was pleased to confirm the teaching of these holy men of old, that if their hearers believed them not, they might believe the works.
