19 And the sons of the captivity kept the passover upon the fourteenth day of the first month. 20 For the priests and the Levites were purified together, all of them were pure, and killed the passover for all the sons of the captivity and for their brethren, the priests, and for themselves. 21 And the sons of Israel who had returned out of captivity and all those who had separated themselves unto them from the uncleanness of the Gentiles of the land, to seek the LORD God of Israel, ate 22 and kept the feast of unleavened bread seven days with joy; for the LORD had made them joyful and turned the heart of the king of Assyria unto them, to strengthen their hands in the work of the house of God, the God of Israel.
