'Insist' in the Bible

But when I saw that they were not acting consistently with the truth of the gospel, I told Cephas in front of everyone, "Though you are a Jew, you have been living like a gentile and not like a Jew. So how can you insist that the gentiles must live like Jews?"

Again, I insist that everyone who allows himself to be circumcised is obligated to obey the entire Law.
