2 Corinthians 9:2-6

for I know your willingness, of which I boast about you to the Macedonians, namely, that Achaia has been prepared since last year, and your zeal has stirred up most of them.

But I have sent the brothers, in order that our boasting about you may not prove empty in this case, so that, as I was saying, you will be prepared;

otherwise, if any Macedonians come with me and find you unprepared, we—not to mention you—would be put to shame by this confidence.

So I considered it necessary to urge the brothers that they go on ahead to you and arrange in advance your previously promised generous gift, that the same would be ready as a generous gift, and not as one grudgingly given due to greediness.

Now I say this: the one who sows sparingly will also reap sparingly, and the one who sows generously will also reap generously.
