2 Corinthians 8:7-8

King James Version

⁷ Therefore, as ye abound in every thing, in faith, and utterance, and knowledge, and in all diligence, and in your love to us, see that ye abound in this grace also.

⁸ I speak not by commandment, but by occasion of the forwardness of others, and to prove the sincerity of your love.
