Some Jews - traveled to Iconium to oppose Paul and the gospel. They had a mission to stop it. I relate these "some Jews" to some Christians. It's not everyone but there are some in the church that go out of their way to oppose the gospel moving forward. They preach tradition and conformity. They throw stones of accusations. I don't want to be part of this group.
Believers Gathered - there are powerful things that happen when the people that believe gather together. Things come back to life. The broken and bruised are healed and restored. Encouragement come from a gathering of believers.
He, being Paul - Notice that Paul was stoned for preaching the gospel. Some say he was dead. But when he got back up (maybe even back from the dead) he went back into the city, the same place he was stoned. Maybe it was a show of Power. The Power of the gospel will move forward. The power of the Holy Spirit > is He who is in you than he who is in the world. The power of passion for e mission of God.
Which are you?
