2 Corinthians 12:16-18

12:16 But be that as it may, I have not burdened you. Yet because I was a crafty person, I took you in by deceit! 12:17 I have not taken advantage of you through anyone I have sent to you, have I? 12:18 I urged Titus to visit you and I sent our brother along with him. Titus did not take advantage of you, did he? Did we not conduct ourselves in the same spirit? Did we not behave in the same way?

Philippians 2:20-21

2:20 For there is no one here like him who will readily demonstrate his deep concern for you. 2:21 Others are busy with their own concerns, not those of Jesus Christ.
