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 complete your share in this ministry of giving.
16 I am thankful to God that he has given Titus the same enthusiasm for you that I have. 17 He welcomed our request that he visit you again. In fact, he himself was eager to go and see you.
