'Matter' in the Bible

I went up [to Jerusalem] because of a [divine] revelation, and I put before them the gospel which I preach among the Gentiles. But I did so in private before those of reputation, for fear that I might be running or had run [the course of my ministry] in vain.

I have confidence in you in the Lord that you will adopt no other view [contrary to mine on the matter]; but the one who is disturbing you, whoever he is, will have to bear the penalty.
