What is a notable event that resumed around 520 BC during the rebuilding of the Temple?

The notable event that resumed around 520 BC during the rebuilding of the Temple was the calling to resume Cyrus' decree. This decree, originally issued by Cyrus the Great, permitted the exiled Jews to return to Jerusalem and rebuild the Temple. After a period of halted construction due to opposition and discouragement, leaders like Haggai and Zechariah encouraged the people to resume their efforts, leading to the revival of the project and the eventual completion of the Second Temple.

This context is significant, as it demonstrates the restoration of worship and the importance of the Temple in Jewish life after the Babylonian exile. The emphasis on fulfilling Cyrus' decree reflects the historical and theological themes of hope and renewal that were critical during this period.
