'Frivolous' in the Bible

O Timothy, guard the truths entrusted to you, shunning irreligious and frivolous talk, and controversy with what is falsely called 'knowledge';

But from irreligious and frivolous talk hold aloof, for those who indulge in it will proceed from bad to worse in impiety,

knowing, as you do, that it was not with a ransom of perishable wealth, such as silver or gold, that you were set free from your frivolous habits of life which had been handed down to you from your forefathers,

For, while they pour out their frivolous and arrogant talk, they use earthly cravings--every kind of immorality--as a bait to entrap men who are just escaping from the influence of those who live in error.
