2 Chronicles 35:1-8

1 King Josiah celebrated the Passover at Jerusalem in honor of the Lord; on the fourteenth day of the first month they killed the animals for the festival.
2 He assigned to the priests the duties they were to perform in the Temple and encouraged them to do them well.
3 He also gave these instructions to the Levites, the teachers of Israel, who were dedicated to the Lord: "Put the sacred Covenant Box in the Temple that King Solomon, the son of David, built. You are no longer to carry it from place to place, but you are to serve the Lord your God and his people Israel.
4 Take your places in the Temple by clans, according to the responsibilities assigned to you by King David and his son King Solomon, 1
5 and arrange yourselves so that some of you will be available to help each family of the people of Israel.
6 You are to kill the Passover lambs and goats. Now make yourselves ritually clean and prepare the sacrifices in order that your fellow Israelites may follow the instructions which the Lord gave through Moses."
7 For the use of the people at the Passover, King Josiah contributed from his own herds and flocks 30,000 sheep, lambs, and young goats, and 3,000 bulls.
8 His officials also made contributions for the people, the priests, and the Levites to use. And the officials in charge of the Temple - Hilkiah, the High Priest, Zechariah, and Jehiel - gave the priests 2,600 lambs and young goats and 300 bulls for sacrifices during the festival.
