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

6 So that we prayed Titus, that as he began, so also he perform in you this grace.
16 And I do thankings to God, that gave the same busyness for you in the heart of Titus, 17 for [soothly] he received exhortation; but when he was busier, by his will he went forth to you [with his will he went forth to you].
