2 Corinthians 8:2-5

how that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality. For to their power, I bear record, yea, and beyond their power they were willing of themselves; praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints. And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.
