2 Corinthians 1:17-19

17 When I therefore was thus determined, did I show fickleness? Or the things that I purpose, do I purpose according to the flesh, that with me there should be the “Yes, yes” and the “No, no?”

18 But as God is faithful, our word towards you was not “Yes and no.”

19 For the Son of God, Yeshua the Messiah, who was preached amongst you by us, by me, Silvanus, and Timothy, was not “Yes and no,” but in him is “Yes.”
