Ezra 6:20-22

New Revised Standard Version Catholic Edition

²⁰ For both the priests and the Levites had purified themselves; all of them were clean. So they killed the passover lamb for all the returned exiles, for their fellow priests, and for themselves. ²¹ It was eaten by the people of Israel who had returned from exile, and also by all who had joined them and separated themselves from the pollutions of the nations of the land to worship the Lord, the God of Israel. ²² With joy they celebrated the festival of unleavened bread seven days; for the Lord had made them joyful, and had turned the heart of the king of Assyria to them, so that he aided them in the work on the house of God, the God of Israel.
