9 "Command Aaron and his sons, saying, This is the law of the burnt offering. The burnt offering shall be on the hearth upon the altar all night until the morning, and the fire of the altar shall be kept burning on it. 10 And the priest shall put on his linen garment, and put his linen breeches upon his body, and he shall take up the ashes to which the fire has consumed the burnt offering on the altar, and put them beside the altar. 11 Then he shall put off his garments, and put on other garments, and carry forth the ashes outside the camp to a clean place. 12 The fire on the altar shall be kept burning on it, it shall not go out; the priest shall burn wood on it every morning, and he shall lay the burnt offering in order upon it, and shall burn on it the fat of the peace offerings. 13 Fire shall be kept burning upon the altar continually; it shall not go out.

Matthew Henry's Commentary on Leviticus 6:9-13

Commentary on Leviticus 6:8-13

(Read Leviticus 6:8-13)

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, 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.
