Acts 16:6 provides the prior context: they were forbidden to preach in Asia, setting up the attempt to enter Bithynia in verse 7.

Acts 8:29 also records the Spirit directing a mission — to Philip rather than Paul. Both show the Spirit's active guidance.

Acts 10:19 has the Spirit telling Peter to go to Cornelius — another example of divine direction, though a command not a prohibition.

Acts 11:12 repeats the Spirit's instruction to Peter about Cornelius, reinforcing the theme of Spirit-guided missions in Acts.

Acts 13:2 records the Spirit commanding the church to set apart Barnabas and Saul — a different mode of guidance but still the Spirit speaking.

1 Peter 1:1 addresses Christians in Bithynia, indicating the gospel later reached that region despite the prohibition.

Romans 1:13 shows Paul's plans to visit Rome hindered, similar to being blocked from Bithynia — both illustrate missionary setbacks.
