Ezra 6:15-18

15The Temple was completed on the third day of the month of Adar, which was in the sixth year of the reign of King Darius.

16Then the sons of Israel—the kohanim, the Levites, and the rest of the exiles— celebrated the dedication of the House of God with joy.

17For the dedication of this House of God they offered 100 bulls, 200 rams, 400 male lambs, and, as a sin offering for all Israel, twelve male goats, corresponding to the number of the tribes of Israel.

18They appointed the kohanim in their divisions and the Levites in their divisions over the service of God at Jerusalem, as it is written in the book of Moses.
