2 Chronicles 35:7-8

35:7 From his own royal flocks and herds, Josiah supplied the people with 30,000 lambs and goats for the Passover sacrifice, as well as 3,000 cattle. 35:8 His officials also willingly contributed to the people, priests, and Levites. Hilkiah, Zechariah, and Jehiel, the leaders of God’s temple, supplied 2,600 Passover sacrifices and 300 cattle.

2 Chronicles 35:12-18

35:12 They reserved the burnt offerings and the cattle for the family divisions of the people to present to the Lord, as prescribed in the scroll of Moses. 35:13 They cooked the Passover sacrifices over the open fire as prescribed and cooked the consecrated offerings in pots, kettles, and pans. They quickly served them to all the people. 35:14 Afterward they made preparations for themselves and for the priests, because the priests, the descendants of Aaron, were offering burnt sacrifices and fat portions until evening. The Levites made preparations for themselves and for the priests, the descendants of Aaron. 35:15 The musicians, the descendants of Asaph, manned their posts, as prescribed by David, Asaph, Heman, and Jeduthun the king’s prophet. The guards at the various gates did not need to leave their posts, for their fellow Levites made preparations for them. 35:16 So all the preparations for the Lord’s service were made that day, as the Passover was observed and the burnt sacrifices were offered on the altar of the Lord, as prescribed by King Josiah. 35:17 So the Israelites who were present observed the Passover at that time, as well as the Feast of Unleavened Bread for seven days. 35:18 A Passover like this had not been observed in Israel since the days of Samuel the prophet. None of the kings of Israel had observed a Passover like the one celebrated by Josiah, the priests, the Levites, all the people of Judah and Israel who were there, and the residents of Jerusalem.
