Ezra 6:21-22

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 corrupt practices to worship the LORD, the God of Israel. Then they celebrated the Festival of Unleavened Bread for seven days. There was great joy throughout the land because the LORD had caused the king of Assyria to be favorable to them, so that he helped them to rebuild the Temple of God, the God of Israel.
