1 Corinthians 9:6 - Coke's Commentary on the Holy Bible

Or I only, and Barnabas— From this expression one would think that the Judaizing Christians, who were the main cause of St. Paul's uneasiness in this respect, had a peculiar spleen against these two Apostles of the uncircumcision; who were so instrumental in procuring and publishing theJerusalem decree, which determined the controversy so directly in favour of the believing Gentiles. It seems probable, from 1 Corinthians 9:12, that Barnabas supported himself by the labour of his hands when at Corinth, as well as St. Paul. See Wall, Whitby, and Calmet.
