8 And he entered the synagogue and for three months spoke boldly, arguing and pleading about the kingdom of God; 9 but when some were stubborn and disbelieved, speaking evil of the Way before the congregation, he withdrew from them, taking the disciples with him, and argued daily in the hall of Tyran'nus. 10 This continued for two years, so that all the residents of Asia heard the word of the Lord, both Jews and Greeks. 11 And God did extraordinary miracles by the hands of Paul, 12 so that handkerchiefs or aprons were carried away from his body to the sick, and diseases left them and the evil spirits came out of them.

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.
