Ezra 6:16-21

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.

19The exiles celebrated the Passover on the fourteenth day of the first month,

20for every one of the kohanim and the Levites had purified themselves and all of them were ceremonially pure. They slaughtered the Passover lamb for all the exiles, and for their fellow kohanim and for themselves.

21So those of Bnei-Yisrael who had returned from the exile ate it, together with all who had separated themselves from the impurity of the nations of the land to seek Adonai the God of Israel.
