2 Corinthians 12:13-14

For what is there wherein ye were made inferior to the rest of the churches, except it be that I myself was not a burden to you? forgive me this wrong. Behold, this is the third time I am ready to come to you; and I will not be a burden to you: for I seek not yours, but you: for the children ought not to lay up for the parents, but the parents for the children.
