Twice

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; and to the other the savour of life unto life. 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…2 Corinthian 2:15-17 (KJV)
