Paul presents ideas that people might have after they hear what he wrote in chapter 2. He does this in order to respond to them in verse 2. AT: "Some people might say, 'Then what advantage does the Jew have? And what is the benefit of circumcision?'" or "Some people might say, 'If that is true, then the Jews do not have any advantage, and there is no benefit in being circumcised.'"
