The so-called Gabriel Stone, said to have been found 13 years ago in Jordan, features an unknown prophetic text from the time of the Second Jewish Temple, which some researchers claim references a messianic resurrection pre-dating Jesus.
Scholars say it as a portal into the religious ideas circulating in the Holy Land in the era when was Jesus was born.
Its form is also unique - it is ink written on stone, not carved - and no other such religious text has been found in the region.
Curators at the Israel Museum, where the first exhibit dedicated to the stone opened today, say it is the most important document found in the area since the discovery of the Dead Sea Scrolls.
'The Gabriel Stone is in a way a Dead Sea Scroll written on stone,' said James Snyder, director of the Israel Museum.
The writing dates to the same period, and uses the same tidy calligraphic Hebrew script, as some of the Dead Sea Scrolls, a collection of documents that include the earliest known surviving manuscripts of Hebrew Bible texts.
