'Passover offerings' in the Bible

Then Josiah contributed to the lay people, to all who were present, flocks of lambs and young goats numbering 30,000, all as Passover offerings, and 3,000 bulls—these were from the king’s property.

His officers also contributed a voluntary offering to the people, the priests and the Levites. Hilkiah, Zechariah, and Jehiel, the officials of the house of God, gave to the priests for the Passover offerings 2,600 from the flocks [of lambs and young goats], and 300 bulls.

Conaniah also, and Shemaiah and Nethanel, his brothers, and Hashabiah and Jeiel and Jozabad, officers of the Levites, contributed to the Levites for the Passover offerings 5,000 from the flocks [of lambs and young goats], and 500 bulls.
