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

6 So we have urged Titus, who encouraged your giving in the first place, to return to you and encourage you to finish this ministry of giving.
16 But thank God! He has given Titus the same enthusiasm for you that I have. 17 Titus welcomed our request that he visit you again. In fact, he himself was very eager to go and see you.
