Command Aaron and his sons, saying, This is the {d} law of the burnt offering: It is the burnt offering, because of the burning upon the altar all night unto the morning, and the fire of the altar shall be burning in it.

(d) That is, the ceremony which ought to be observed in it.

Wesley's Notes

6:9 And the Lord spake - Hitherto he hath prescribed the sacrifices themselves; now he comes to the manner of them. The burnt - offering - The daily one, which Exo 29:38, Num 28:3, as the following words shew. This was to be so managed and laid on piece after piece, that the fire might be constantly maintained by it. The morning burnt - offerings were to be kept burning all the day from morning to night also; but he mentions not that, because there was such a constant succession of sacrifices in the day - time that there needed no law for feeding and keeping in the fire then; the only danger was for the night, when other sacrifices were not offered, but only the evening burnt - offering, which if it had been consumed quickly, as the morning burnt - offering was, there had been danger of the going out of that fire, which they were commanded diligently and constantly to keep in.

Jamieson-Fausset-Brown Bible Commentary

9. Command Aaron and his sons, saying, This . law of the burnt offering-In this passage Moses received instructions to be delivered to the priests respecting their official duties, and first the burnt offering-Hebrew, "a sacrifice, which went up in smoke." The daily service consisted of two lambs, one offered in the morning at sunrise, the other in the evening, when the day began to decline. Both of them were consumed on the altar by means of a slow fire, before which the pieces of the sacrifice were so placed that they fed it all night. At all events, the observance of this daily sacrifice on the altar of burnt offering was a daily expression of national repentance and faith. The fire that consumed these sacrifices had been kindled from heaven at the consecration of the tabernacle [Le 9:24], and to keep it from being extinguished and the sacrifices from being burned with common fire, strict injunctions are here given respecting not only the removal of the ashes [Le 6:10, 11], but the approaching near to the fireplace in garments that were not officially "holy."

Matthew Henry's Concise Commentary

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, 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.
