Acts 18:1, 4–11
After this Paul left Athens and went to Corinth. … 4 And he reasoned in the synagogue every Sabbath, and tried to persuade Jews and Greeks. 5 When Silas and Timothy arrived from Macedonia, Paul was occupied with the word, testifying to the Jews that the Christ was Jesus. 6 And when they opposed and reviled him, he shook out his garments and said to them, “Your blood be on your own heads! I am innocent. From now on I will go to the Gentiles.” 7 And he left there and went to the house of a man named Titius Justus, a worshiper of God.

1 Thessalonians 2:2, 4-6
But though we had already suffered and been shamefully treated at Philippi, as you know, we had boldness in our God to declare to you the gospel of God in the midst of much conflict. … 4 but just as we have been approved by God to be entrusted with the gospel, so we speak, not to please man, but to please God who tests our hearts. 5 For we never came with words of flattery, as you know, nor with a pretext for greed—God is witness. 6 Nor did we seek glory from people, whether from you or from others …
