Leviticus 19: Thou shalt not steal, nor lie, nor deal falsely with thy neighbor. Thou shalt not swear falsely by the name of the Lord thy God. Thou shalt not oppress thy neighbor, nor rob him. Thou shalt not deal falsely with thy neighbor, nor oppress him. Thou shalt not curse the deaf, nor put a stumbling block before the blind. Thou shalt not do unto others what you wouldn't want done unto you. And thou shalt love thy neighbor as thyself. In other words, don't be a jerk.
