2 Corinthians 11:6-7

New International Version

⁶ I may indeed be untrained as a speaker,^(A) but I do have knowledge.^(B) We have made this perfectly clear to you in every way. ⁷ Was it a sin^(C) for me to lower myself in order to elevate you by preaching the gospel of God^(D) to you free of charge?^(E)
