'Passover offerings' in the Bible

And Josiah gave for the children of the people a heave-offering of the flocks, lambs and goats, all for the passover-offerings, for all that were present to the number of thirty thousand, and three thousand bullocks: these were of the king's substance.

And his princes gave a voluntary heave-offering for the people, for the priests, and for the Levites: Hilkijah and Zechariah and Jehiel, rulers of the house of God, gave to the priests for the passover-offerings two thousand six hundred small cattle and three hundred oxen;

and Conaniah, and Shemaiah and Nethaneel, his brethren, and Hashabiah and Jeiel and Jozabad, chief of the Levites, gave as heave-offering to the Levites for the passover-offerings five thousand small cattle and five hundred oxen.
