Parallel
Ezra 6:20

For the priests and Levites were purified, all were clean to a man, and they slew the passover for all the children of the captivity, and for their brethren the priests, and for themselves.
All the priests and Levites had purified themselves and were ceremonially clean. And the Levites slaughtered the Passover lamb for all the exiles, for their priestly brothers, and for themselves.
