The period is understood to run from the 9th millennium BC, which corresponds to the earliest dated Neolithic remains of Jericho, to 700 AD, which marks the first invasions by Muslim armies. This time period is considered by some authorities to be too wide and controversial. A second narrower period has been described that is more closely defined by the biblical stories: from the middle Bronze Age, that is from 2000 BC, which according to Biblical chronology corresponds with the time of the Patriarchs (Abraham, Isaac and Jacob) until the end of the 1st century AD, with the death of the last apostle John the Evangelist and the end of the so-called Apostolic Church.
