1 Corinthians 1:14-17 NASB
I thank God that I baptized none of you except Crispus and Gaius, so that no one would say you were baptized in my name. Now I did baptize also the household of Stephanas; beyond that, I do not know whether I baptized any other. For Christ did not send me to baptize, but to preach the gospel, not in cleverness of speech, so that the cross of Christ would not be made void.
