1 Corinthians 15:11 in the King James Version
Therefore whether it were I or they, so we preach, and so ye believed.
Context
10 But by the grace of God I am what I am. His grace which was given to me was not futile, but I worked more than all of them; yet not I, but the grace of God which was with me.
11 Whether then it is I or they, so we preach, and so you believed.
12 Now if Christ is preached, that he has been raised from the dead, how do some among you say that there is no resurrection of the dead?
