2 Corinthians 9:4-7

4lest by any means, if there come with me any of Macedonia and find you unprepared, we (that we say not, ye) should be put to shame in this confidence. 5I thought it necessary therefore to entreat the brethren, that they would go before unto you, and make up beforehand your aforepromised bounty, that the same might be ready as a matter of bounty, and not of extortion.

6But thisI say, He that soweth sparingly shall reap also sparingly; and he that soweth bountifully shall reap also bountifully. 7Let each man do according as he hath purposed in his heart: not grudgingly, or of necessity: for God loveth a cheerful giver.
