2 Corinthians 1:16-18

16 and to pass by you into Macedonia and to come again out of Macedonia unto you and of you to be sent forward to Judaea.

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 of me there should be yes, yes, and no, no?

18 But God [is] faithful that our word toward you has not been yes and no.
