2 Corinthians 1:16 Meaning

14As also ye have acknowledged us in part, that we are your rejoicing, even as ye also are our's in the day of the Lord Jesus.

15And in this confidence I was minded to come unto you before, that ye might have a second benefit;

16And to pass by you into Macedonia, and to come again out of Macedonia unto you, and of you to be brought on my way toward Judaea.

17When 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?

18But as God is true, our word toward you was not yea and nay.
