2 Corinthians 8:6; 2 Corinthians 8:16-17

6 Insomuch that we exhorted Titus, that as he made a beginning before, so he would also complete in you this grace.

16 But thanks be to God, who puts the same earnest care for you into the heart of Titus.

17 For he indeed accepted our exhortation, but being himself very earnest, he went forth to you of his own accord.
