So back to the Jewish temple at Elephantine....
Who were these Jews? from the surviving documentation it appears that they were a group of Jewish mercenaries. At first, it is thought, they were in the employ of the Egyptians and were absorbed by the Iranians (Persians) when Cambyses II of Persia conquered Egypt in 525 BCE.
The discovery of papyri from that site has provided us with a lot of information about these Jewish worshippers of YHWH:
Quote (from Rosenberg's article):
"The papyri, written in Aramaic, are judicial and family documents that list property and marriage contracts and describe the colony's temple, where sacrifices were offered to YHW (Yahweh). One well-known document, known as the Passover Papyrus (dated to 419 BCE), sets out instructions to the colony in the name of Darius II to celebrate the feast of Unleavened Bread on the 14th of Nissan (the first month of Spring) and to drink no beer for seven days. Another papyrus records the destruction of the temple by the Egyptian priests of the nearby temple of Khnum in 410 BCE and the subsequent permission given for it to be rebuilt four years later (Porten 1968: 295)."
Perhaps the most important thought we can learn from this temple's existence is that temple worship need not have been confined to the Jerusalem temple.
In Marty E. Stevens exhaustive study of temple worship in west Asia (Temples,Tithes and Taxes: The Temple and the Economic Life of Ancient Israel, Publisher: Hendrickson, 2006, pp. 59-63) she lists five temples outside of Jerusalem.
In the Palestine area, there is one at Mt Gerizim, that Josephus described as being modelled on the Jerusalem temple.
Another at Arad in the Negev resembles the layout of the Jerusalem Temple. records recovered from the site indicate a connection with the Jerusalem Temple.
There are two more in the northern kingdom at Dan and Bethel.
And finally, the two in Egypt, the building at Elephantine, and the second mentioned in my first post but not discussed. It was built at Leontopolis in northern Egypt by High Priest Onias IV, circa 150BCE and also modelled on the Jerusalem temple and likely served Jews who lived in Egypt.
