Ezra 5:1

Then the prophets, Haggai, the prophet, and Zechariah, the son of Iddo, prophesied unto the Jews that were in Judah and Jerusalem in the name of the God of Israel, even unto them. It seems that the Jews, after their first attempt to rebuild the Temple had been hindered, had lost most of their interest and zeal for the task, and needed an emphatic admonition to arouse them to action again, Haggai 1:2.
