NET
17 Therefore when I was planning to do this, I did not do so without thinking about what I was doing, did I? Or do I make my plans according to mere human standards so that I would be saying both “Yes, yes” and “No, no” at the same time?
Darby
17 Having 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?
KJV
17 When I therefore was thus minded, did I use lightness? or the things that I purpose, do I purpose according to the flesh, that with me there should be yea yea, and nay nay?
