2 Corinthians 8:7-9

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. I speak not by commandment, but by occasion of the forwardness of others, and to prove the sincerity of your love. For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might be rich.
