Ezra 6:21-22

New International Version - UK

²¹ So the Israelites who had returned from the exile ate it, together with all who had separated themselves from the unclean practices of their Gentile neighbours in order to seek the Lord, the God of Israel. ²² For seven days they celebrated with joy the Festival of Unleavened Bread, because the Lord had filled them with joy by changing the attitude of the king of Assyria so that he assisted them in the work on the house of God, the God of Israel.
