'Mind' in the Bible

and He must not be a new convert, so that he will not [behave stupidly and] become conceited [by appointment to this high office] and fall into the [same] condemnation incurred by the devil [for his arrogance and pride].

and perpetual friction between men who are corrupted in mind and deprived of the truth, who think that godliness is a source of profit [a lucrative, money-making business—withdraw from them].
