2 Chronicles 31:2-3

2Hezekiah put the priests and the Levites into several groups. Each group had special work to do. Their different jobs were to offer burnt offerings and friendship offerings, and to serve God in other ways. Some of them would thank the Lord and sing songs to praise him at the gates of his temple.

3The king gave some of his own animals for burnt offerings. The priests offered these sacrifices in the way that the law of the Lord taught. They offered burnt offerings each morning and each evening. They also offered them on Sabbath days, on the days of New Moon festivals and on other special days.
