2 Corinthians 2 (KJV)

11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.

15 For we are unto God a sweet savour of Christ, in them that are saved, and in them that perish:
16 To the one we are the savour of death unto death (SATAN); and to the other the savour of life unto life (JESUS). And who is sufficient for these things?

17 For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
