On April 21 the returned exiles celebrated Passover.
The priests and Levites had purified themselves and were ceremonially clean. So they slaughtered the Passover lamb for all the returned exiles, for the other priests, and for themselves.
The Passover meal was eaten by the people of Israel who had returned from exile and by the others in the land who had turned from their immoral customs to worship the LORD, the God of Israel.
They ate the Passover meal and celebrated the Festival of Unleavened Bread for seven days. There was great joy throughout the land because the LORD had changed the attitude of the king of Assyria toward them, so that he helped them to rebuild the Temple of God, the God of Israel.
