2 Chronicles 30:15
they slaughtered the Passover lambs on the fourteenth of the second month. And the priests and Levites were ashamed of themselves, and consecrated themselves and brought burnt offerings to the house of the Lord.
You shall keep it until the fourteenth day of the same month, then the whole assembly of the congregation of Israel is to kill it at twilight.
For the priests and the Levites had purified themselves together; all of them were pure. Then they slaughtered the Passover lamb for all the exiles, both for their brothers the priests and for themselves.
