After dealing in the first 10 chapters with the chronology of the period from the creation of the world to the death of Moses, the writer proceeds to determine the dates of the events which occurred after the Israelites, led by Joshua, entered the Holy Land. Here Biblical chronology presents many difficulties, dates not being clearly given, and in many cases "Seder Olam" was used by later Biblical commentators as a basis of exegesis. It is known that from the entry of the Israelites into the Holy Land to the time of Jephthah a period of 300 years elapsed. By computing the life periods of the Judges and assuming that Jephthah sent his message (alluding to the 300 years) in the second year of his rule, "Seder Olam" concludes that the reign of Joshua lasted 28 years. The work places two events in the Book of Judges whose date is unclear (the making of the image for Micah and Battle of Gibeah episode) in the time of Othniel.
