New discovery concerning the Exodus:
The Problem
  If one attempts to harmonize biblical and secular histories, working  back from the time of Christ, little difficulty is encountered until one  gets back prior to the United Kingdom (i.e., until before the time when  Saul became King of Israel). There is no doubt that the central people  and places named in the New Testament existed, for example, and a number  of Israel's kings are named in the literature of surrounding countries.
  But when one begins to work back much prior to the United Kingdom  period the picture changes completely. For example: none of the  prominent figures of the Exodus can be positively identified in secular  records; the chronology and history of Egypt seem incompatible with the  biblical account; the archaeology of Jericho cannot be made to fit the  biblical record of Joshua's defeat of that city without sacrificing  biblical and scientific integrity; and the situation at Ai is even less  workable. The trail of harmony between biblical and secular history is  lost as one moves back into the period of the judges.  
   This problem is widely recognized. In fact, the majority of scholars  today have concluded that the Bible is simply not historically reliable  before the United Kingdom period. They explain away the earlier portions  of the Bible as folktales bearing little if any resemblance to real  history.  Until recently, conservative, Bible-believing scholarship has  been in a difficult position. If the Bible tells an accurate story of  history, why do archaeology and the Bible not agree prior to the United  Kingdom period?
  
The Solution
   Gerald E. Aardsma, Ph.D., has proposed that this apparent disharmony  results from a problem in traditional biblical chronology.  Traditional  biblical chronologies are constructed by assembling the various  chronological data given in the Bible itself. Interpretive issues have  given rise to relatively minor variations in traditional biblical  chronologies, depending on the scholar.  The traditional chronology  displayed in the time chart at left is typical.  
 The key biblical chronological link used to determine the date  of the Exodus is a number in 1 Kings 6:1.  This verse reads, "And it  came to pass in the four hundred and eightieth year after the children  of Israel were come out of the land of Egypt, in the fourth year of  Solomon's reign over Israel...". Solomon's reign is usually calculated  to have begun around 970 B.C., thus placing the Exodus around 1450 B.C.  As stated above, the archaeology of Egypt and Canaan at this time is  incompatible with the biblical record. In addition, the Bible lists  consecutive events between the Exodus and Solomon's reign which total at  least 
600 years.  
   In 1990, Dr. Aardsma proposed a major adjustment to traditional biblical  chronology. He proposed that the "480" of 1 Kings 6:1 was originally  "1,480" but the Hebrew letters corresponding to the "one thousand" were  lost at an early stage of copying.
   This proposal is applied in the second time chart at left.  The new biblical date for the Exodus becomes 
ca.  2450 B.C., and prior biblical events are similarly shifted to earlier  times, by exactly 1000 years relative to traditional biblical  chronology.
   This change is radical, and at first unimaginable. However, as one  begins to examine the archaeology at the new dates, the harmony between  biblical and secular accounts is overwhelming. Egypt is struck by  national disaster, effectively causing the collapse of the Old Kingdom  at the end of the sixth dynasty. The trail of the Israelites in the  desert at the time of the Exodus, and remains of their encampment dating  to exactly this time period have been found. Both Jericho and Ai were  destroyed 
ca. 2400 B.C., with destruction layers accurately  fitting the biblical descriptions. The evidence that Dr. Aardsma's  proposal is correct has become overwhelming and continues to mount. 
   This discovery and the ensuing research have resolved the conflicts  between biblical and secular histories prior to the United Kingdom  period. Dr. Aardsma's research has also led to many exciting discoveries  surrounding early biblical events such as Noah's Flood. Conservative,  Bible-believing scholarship today has an answer for those who claim that  the Old Testament stories are mere fabrications. This discovery is of  extreme significance to anyone who believes the Bible or studies  biblical archaeology.
