'Idle' in the Bible

For there are many rebellious men who are empty talkers [just windbags] and deceivers; especially those of the circumcision [those Jews who insist that Gentile believers must be circumcised and keep the Law in order to be saved].

One of them [Epimenides, a Cretan], a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.”

Our people must learn to do good deeds to meet necessary demands [whatever the occasion may require], so that they will not be unproductive.
