Darby(i)
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?
18 Now God [is] faithful, that our word to you is not yea and nay.
19 For the Son of God, Jesus Christ, he who has been preached by us among you (by me and Silvanus and Timotheus), did not become yea and nay, but yea *is* in him.
20 For whatever promises of God [there are], in him is the yea, and in him the amen, for glory to God by us.
