2 Corinthians 8:1-5

Moreover, brethren, we make known to you the grace of God which hath been given in the churches of Macedonia; how that in much proof of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality. For according to their power, I bear witness, yea and beyond their power, they gave of their own accord, beseeching us with much entreaty in regard of this grace and the fellowship in the ministering to the saints: and this, not as we had hoped, but first they gave their own selves to the Lord, and to us through the will of God.
