The business conduct of the disciples of wise men is truthful and faithful.... He does not allow himself to be made a surety or a guarantor and does not accept the power of attorney.... He lends money and is gracious. He shall not take away business from his fellow man.
MaimonidesIt is possible that the meaning of wisdom in Hebrew indicates aptitude for stratagems and the application of thought in such a way that the stratagems and ruses may be used in achieving either rational or moral virtues, or in achieving skill in a practical art, or in working evil and wickedness.
