Leviticus 6 - Matthew Henry's Concise Commentary on the Bible

Concerning the burnt-offering.

The daily sacrifice of a lamb is chiefly referred to. The priest must take care of the fire upon the altar. The first fire upon the altar came from heaven, ch. 9:24; by keeping that up continually, all their sacrifices might be said to be consumed with the fire from heaven, in token of God's acceptance. Thus should the fire of our holy affections, the exercise of our faith and love, of prayer and praise, be without ceasing.

(Le 6:14-23)
