In his one speech in Scripture, Stephen made a few flubs about some incidentals in the lives of Abraham and Jacob. Clearly Stephen did not know this cluster of facts thoroughly.

Apart from that, you’ve mentioned two of Paul’s reports about his conversion where Paul’s misspeaking is a possibility. But in those cases, there are other plausible explanations for the alleged error.

Even without assuming that the Apostles received divine guidance that render the NT inerrant, I tend to prefer an account that does not assume that Paul misspoke in those two cases. He’s recounting an event that occurred in his own life. Indeed, he’s recounting the pivotal event in his life. He is not relating some piece of trivia about events 1200 years in the past. It’s unlikely he got those details wrong.

Were there other examples of reported speech that contain errors that we are missing?
