'Passover offerings' in the Bible

for many are in the assembly who have not sanctified themselves, and the Levites are over the slaughtering of the passover-offerings for every one not clean, to sanctify him to Jehovah:

And Josiah lifteth up to the sons of the people a flock of lambs and young goats, the whole for passover-offerings, for every one who is found, to the number of thirty thousand, and oxen three thousand: these are from the substance of the king.

And his heads, for a willing-offering to the people, to the priests, and to the Levites, have lifted up; Hilkiah, and Zechariah, and Jehiel, leaders in the house of God, to the priests have given for passover-offerings two thousand and six hundred, and oxen three hundred;

and Conaniah, and Shemaiah, and Nethaneel, his brethren, and Hashabiah, and Jeiel, and Jozabad, heads of the Levites, have lifted up to the Levites, for passover-offerings, five thousand, and oxen five hundred.
