It seems likely that synagogues were instituted during the 70 - year Babylonian exile when there was no temple in existence or shortly after the return from exile while the temple was being reconstructed.
Tundub tõenäoline, et sünagoogid kujunesid 70 - aastase Babüloonia pagenduse ajal, mil polnud templit, või pisut pärast pagendusest naasmist sel ajal, kui templit taastati.
