1Th 4:11 And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
2Th 3:12 Now them that are such we command and exhort by our Lord Jesus Christ, that with quietness they work, and eat their own bread.
2Th 3:10 For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
Seems telling to me that Paul practiced what he preached...
Act 18:1 After these things Paul departed from Athens, and came to Corinth;
Act 18:2 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.
Act 18:3 And because he was of the same craft, he abode with them, and wrought: for by their occupation they were tentmakers.
Act 18:4 And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
He worked as a tentmaker and preached on the Sabbath.
