Passover: The Lamb Killed by Levites, for Those Who Were Ceremonially Unclean

Since there were many in the assembly who had not consecrated themselves, the Levites were in charge of slaughtering the Passover lambs for every unclean person to consecrate the lambs to the LORD.

To the Levites who taught all Israel and were holy to the LORD, Josiah said: “Put the holy ark in the temple built by Solomon son of David king of Israel. It is not to be carried around on your shoulders. Now serve the LORD your God and His people Israel. …

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.
