2 Corinthians 1:15-20

15And in this confidence I was minded to come first unto you, that ye might have a second benefit; 16and by you to pass into Macedonia, and again from Macedonia to come unto you, and of you to be set forward on my journey unto Judæa. 17When I therefore was thus minded, did I show fickleness? or the things that I purpose, do I purpose according to the flesh, that with me there should be the yea yea and the nay nay? 18But as God is faithful, our word toward you is not yea and nay. 19For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timothy, was not yea and nay, but in him is yea. 20For how many soever be the promises of God, in him is the yea: wherefore also through him is the Amen, unto the glory of God through us.
