“For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timotheus, was not yea and nay, but in him was yea.”
King James Version (KJV)
1:19 For Jesus Christ, who was preached by us - That is, our preaching concerning him. Was not yea and nay - Was not variable and inconsistent with itself. But was yea in him - Always one and the same, centering in him.
2Co 1:19 For the Son of God . . . was not yea and nay. The idea is that there was no vacillation and uncertainty about Paul's preaching when he was in Corinth. But in him was yea. There was positive affirmation.
