1 Corinthians 1:14-16

Young's Literal Translation

¹⁴ I give thanks to God that no one of you did I baptize, except Crispus and Gaius --

¹⁵ that no one may say that to my own name I did baptize;

¹⁶ and I did baptize also Stephanas' household -- further, I have not known if I did baptize any other.
