1 Corinthians 4:10-13, Working With Our Own Hands
When the Apostle Paul first came to Corinth, he worked as a tent-maker for his subsistence and preached in the synagogue on the Sabbath.
Luke wrote in Acts 18:1-4 After these things Paul departed from Athens, and came to Corinth; 2 And found a certain Jew named Aquila, born in Pontus, lately come from Italy, with his wife Priscilla; (because that Claudius had commanded all Jews to depart from Rome:) and came unto them. 3 And because he was of the same craft, he abode with them, and wrought: for by their occupation they were tentmakers. 4 And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
