Ezra 6:18

16The children of Israel, the priests, the Levites, and the rest of the children of the captivity, kept the dedication of this house of God with joy.

17They offered at the dedication of this house of God one hundred bulls, two hundred rams, four hundred lambs; and for a sin offering for all Israel, twelve male goats, according to the number of the tribes of Israel.

18They set the priests in their divisions and the Levites in their courses, for the service of God which is at Jerusalem, as it is written in the book of Moses.

19The children of the captivity kept the Passover on the fourteenth day of the first month.

20Because the priests and the Levites had purified themselves together, all of them were pure. They killed the Passover for all the children of the captivity, for their brothers the priests, and for themselves.
