'Decided' in the Bible

Paul and Barnabas disagreed greatly and debated with them, so it was determined that Paul and Barnabas and some of the others from their group would go up to Jerusalem to the apostles and the elders [and confer with them] concerning this issue.

[However, Silas decided to stay there.]

As they traveled from town to town, they delivered the decrees decided on by the apostles and elders who were in Jerusalem, for the churches to observe.

But if you want anything beyond this, it will be settled in the lawful assembly.
