The activity of Haggai can be dated quite precisely to the year 520 BC, almost two decades after the return of the Jews from the Babylonian exile. During that time various problems had beset the returned exiles, and they had not succeeded in rebuilding the Temple. We know from Ezra 5 , 1f that it was at the urging of Haggai and Zechariah that the task was finally brought to completion. The book of Haggai preserves both the words Haggai used to exhort the Jews to finish the building and his attempt to cope with their disappointment after it was finished.
