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

6 Accordingly, we urged Titus that as he had started, so he should complete among you this act of grace.
16 But thanks be to God, who put into the heart of Titus the same earnest care I have for you. 17 For he not only accepted our appeal, but being himself very earnest he is going to you of his own accord.
