Ezra 6:19-21

New Catholic Bible

¹⁹ The Passover. The exiles celebrated the Passover on the fourteenth day of the first month. ²⁰ For both the priests and the Levites had purified themselves, and they were all ceremonially clean. The Levites sacrificed the Passover lamb for all the exiles who had returned, for their brothers the priests, and for themselves.

²¹ Therefore, the Israelites who had returned from exile, as well as those who had separated themselves from the unclean practices of their Gentile neighbors in order to seek the Lord, the God of Israel, ate the Passover lamb.
