2 Corinthians 8:3-5 New King James Version (NKJV)
3 For I bear witness that according to their ability, yes, and beyond their ability, they were freely willing, 4 imploring us with much urgency that we would receive[a] the gift and the fellowship of the ministering to the saints. 5 And not only as we had hoped, but they first gave themselves to the Lord, and then to us by the will of God.
