2 Corinthians 9:5-6

9:5 Therefore I thought it necessary to urge these brothers to go to you in advance and to arrange ahead of time the generous contribution you had promised, so this may be ready as a generous gift and not as something you feel forced to do. 9:6 My point is this: The person who sows sparingly will also reap sparingly, and the person who sows generously will also reap generously.
