American Standard Version (ASV):
But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Cephas before [them] all, If thou, being a Jew, livest as do the Gentiles, and not as do the Jews, how compellest thou the Gentiles to live as do the Jews?
King James Version (KJV):
But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before [them] all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
