The king contributed some of what he owned for burnt sacrifices, including the morning and evening burnt sacrifices and the burnt sacrifices made on Sabbaths, new moon festivals, and at other appointed times prescribed in the law of the Lord.

He ordered the people living in Jerusalem to contribute the portion prescribed for the priests and Levites so they might be obedient to the law of the Lord.

Preparations were made, and the priests stood at their posts and the Levites in their divisions as prescribed by the king.

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.

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.

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.

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.
