Ezra 6:21-22

Young's Literal Translation

²¹ And the sons of Israel, those returning from the captivity, and every one who is separated from the uncleanness of the nations of the land unto them, to seek to Jehovah, God of Israel, do eat,

²² and they make the feast of unleavened things seven days with joy, for Jehovah made them to rejoice, and turned round the heart of the king of Asshur unto them, to strengthen their hands in the work of the house of God, the God of Israel.
