2 Corinthians 1:15-18

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.
