2 Corinthians 9:5-6

I 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. But this I say, He that soweth sparingly shall reap also sparingly; and he that soweth bountifully shall reap also bountifully.
