This was authorized by Cyrus the King of Persia (600-529 BC) after the return from the exile, (by defeating the Babylonians to end the exile) and was to be 90ft. Square and high. Work was started in the 2nd year after the return, and then was stopped because of the opposition of the Samaritans. It was begun again in 520 BC, and was finished 5 years later. In the end it turned out to be more or less a copy of Solomon's Temple but more modest and less elaborate. Some of the captured Temple vessels were returned. There was the altar of incense, one candlestick, and one table for the shewbread piled up bread. There was also the priests' lodging and the usual courts.
Remember: Cyrus the son of Cambyses was regarded by Isaiah as “the created instrument of God to end the exile”.
