'Churches' in the Bible

We want you to know, brothers, about the grace of God granted to the churches of Macedonia:

We have sent with him the brother who is praised throughout the churches for his gospel ministry.

And not only that, but he was also appointed by the churches to accompany us with this gift that is being administered by us for the glory of the Lord Himself and to show our eagerness to help.

As for Titus, he is my partner and coworker serving you; as for our brothers, they are the messengers of the churches, the glory of Christ.

Therefore, show them proof before the churches of your love and of our boasting about you.

I robbed other churches by taking pay from them to minister to you.

Not to mention other things, there is the daily pressure on me: my care for all the churches.

So in what way were you treated worse than the other churches, except that I personally did not burden you? Forgive me this wrong!
