2 Corinthians 1:15-18

15And with this confidence I purposed to come to you previously, that ye might have a second favour;

16and to pass through to Macedonia by you, and again from Macedonia to come to you, and to be set forward by you to Judaea.

17Having therefore this purpose, did I then use lightness? Or what I purpose, do I purpose according to flesh, that there should be with me yea yea, and nay nay?

18Now 1God [is] faithful, that our word to you is not yea and nay.
