'First' in the Bible

I planned with this confidence to come to you first, so you could have a double benefit,

For the glory of the first no longer seems to be glory, because of the greater glory of that which comes after.

And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.

I give my opinion in this matter, for this is to your advantage, who were the first to begin a year ago not only to do this, but also to desire to do it.

For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath not.

For it is not as though we were overstepping our limits when we came to you. We were the first to reach you with the gospel of the Messiah.
