Book of Haggai
This is in Chapter 1 verses 14 and 15.  The Book of Ezra says that it was finished on February 25 516 BCE "The Temple was completed on the third day of the month Adar, in the sixth year of the reign of King Darius." (Ezra Chapter 6, verse 15) After this Haggai said that God would bless the people. (Chapter 2, verse 18-19) The book ends by telling about the future downfall of other kingdoms.
