G4278–προενάρχομαι–proenarchomai

So that we begged Titus that, according as he had before begun, so he would also complete as to you this grace also;

προενήρξατο proenērxato “he had begun”

And I give [ergänzt: my] opinion in this, for this is profitable for you who began before, not only to do, but also to be willing, a year ago.

προενήρξασθε proenērxasthe “you began before”
