Paul is asking questions the Corinthians might be asking and then answering them to emphasize that he is as much a Jew as the super-apostles are. You should keep the question-and-answer form if possible. Alternate translation: "They want you to think they are important and to believe what they say because they are Hebrews and Israelites and descendants of Abraham. Well, so am I."
