Ezra 6:15-18 YLT

15 And this house hath gone out till the third day of the month Adar, that is [in] the sixth year of the reign of Darius the king.
16 And the sons of Israel have made, [and] the priests, and the Levites, and the rest of the sons of the captivity, a dedication of this house of God with joy,
17 and have brought near for the dedication of this house of God, bullocks a hundred, rams two hundred, lambs four hundred; and young he-goats for a sin-offering for all Israel, twelve, according to the number of the tribes of Israel;
18 and they have established the priests in their divisions, and the Levites in their courses, over the service of God that [is] in Jerusalem, as it is written in the book of Moses.
