2 Chronicles 35:1-6 New International Version - UK (NIVUK)
Josiah celebrates the Passover
35 Josiah celebrated the Passover to the Lord in Jerusalem, and the Passover lamb was slaughtered on the fourteenth day of the first month. 2 He appointed the priests to their duties and encouraged them in the service of the Lord’s temple. 3 He said to the Levites, who instructed all Israel and who had been consecrated to the Lord: ‘Put the sacred ark in the temple that Solomon son of David king of Israel built. It is not to be carried about on your shoulders. Now serve the Lord your God and his people Israel. 4 Prepare yourselves by families in your divisions, according to the instructions written by David king of Israel and by his son Solomon.
5 ‘Stand in the holy place with a group of Levites for each sub-division of the families of your fellow Israelites, the lay people. 6 Slaughter the Passover lambs, consecrate yourselves and prepare the lambs for your fellow Israelites, doing what the Lord commanded through Moses.’
2 Chronicles 35:10-16 New International Version - UK (NIVUK)
10 The service was arranged and the priests stood in their places with the Levites in their divisions as the king had ordered. 11 The Passover lambs were slaughtered, and the priests splashed against the altar the blood handed to them, while the Levites skinned the animals. 12 They set aside the burnt offerings to give them to the sub-divisions of the families of the people to offer to the Lord, as it is written in the Book of Moses. They did the same with the cattle. 13 They roasted the Passover animals over the fire as prescribed, and boiled the holy offerings in pots, cauldrons and pans and served them quickly to all the people. 14 After this, they made preparations for themselves and for the priests, because the priests, the descendants of Aaron, were sacrificing the burnt offerings and the fat portions until nightfall. So the Levites made preparations for themselves and for the Aaronic priests.
15 The musicians, the descendants of Asaph, were in the places prescribed by David, Asaph, Heman and Jeduthun the king’s seer. The gatekeepers at each gate did not need to leave their posts, because their fellow Levites made the preparations for them.
16 So at that time the entire service of the Lord was carried out for the celebration of the Passover and the offering of burnt offerings on the altar of the Lord, as King Josiah had ordered.
