In Nigeria, there are ills which affect the well being of the citizens; corruption has devoured the goodness seen in the country. This problem ranges from social, cultural, educational, political and religiously. This is a cankerworm in the fabric of the country. This research will help to address these ills by looking into the custom of the Old Testament Israel. The researcher adopted a historiographic and phenomenological method of research design and made use of secondary sources like library and online materials for gathering information. The researcher in the course of the research found out that, customs must be followed strictly for good order of the country; also that corruption is the chief cause of these problems in the country. The researcher recommended that the leaders should be Messiahs in their different areas so as to curb these ills. Also, the government should enforce the rule of law and compliance to the letters of the constitution of the country. These will help to guide the behaviour of people in the country.
