Ezra 6:21-22

21The sons of Israel who returned from exile and 1all those who had separated themselves from 2the impurity of the nations of the land to join them, to seek the Lord God of Israel, ate the Passover.

22And 3they observed the Feast of Unleavened Bread seven days with joy, for the Lord had caused them to rejoice, and 4had turned the heart of 5the king of Assyria toward them to 6encourage them in the work of the house of God, the God of Israel.
