The Levites slaughtered^(A) the Passover lamb for all the exiles, for their relatives the priests and for themselves. ²¹ So the Israelites who had returned from the exile ate it, together with all who had separated themselves^(B) from the unclean practices^(C) of their Gentile neighbors in order to seek the Lord,^(D) the God of Israel. ²² For seven days they celebrated with joy the Festival of Unleavened Bread,^(E) because the Lord had filled them with joy by changing the attitude^(F) of the king of Assyria so that he assisted them in the work on the house of God, the God of Israel.
