Ezra 6:17-21

They offered for the dedication of this temple of God a hundred bulls, two hundred rams, four hundred lambs, and as a sin offering for all Israel twelve male goats, corresponding to the number of the tribes of Israel.

Then they appointed the priests to their divisions and the Levites in their sections for the service of God in Jerusalem, as it is written in the Book of Moses. The Passover Held

The exiles held the Passover on the fourteenth of the first month.

For the priests and the Levites had purified themselves together; all of them were pure. Then they slaughtered the Passover lambs for all the exiles, both for their brothers the priests and for themselves.

And the sons of Israel who returned from exile and all those who had separated themselves from the impurity of the nations of the land to join them, to seek the Lord God of Israel, ate the Passover.
