Leviticus 6:8-13

Verse 8

And the Lord spake unto Moses - At this verse the Jews begin the 25th section of the law; and here, undoubtedly, the 6th chapter should commence, as the writer enters upon a new subject, and the preceding verses belong to the fifth chapter. The best edited Hebrew Bibles begin the 6th chapter at this verse.
Verse 9

This is the law of the burnt-offering - This law properly refers to that burnt-offering which was daily made in what was termed the morning and evening sacrifice; and as he had explained the nature of this burnt-offering in general, with its necessary ceremonies, as far as the persons who brought them were concerned, he now takes up the same in relation to the priests who were to receive them from the hands of the offerer, and present them to the Lord on the altar of burnt-offerings.

Because of the burning upon the altar all night - If the burnt-offering were put all upon the fire at once, it could not be burning all night. We may therefore reasonably conclude that the priests sat up by turns the whole night, and fed the fire with portions of this offering till the whole was consumed, which they would take care to lengthen out till the time of the morning sacrifice. The same we may suppose was done with the morning sacrifice; it was also consumed by piecemeal through the whole day, till the time of offering the evening sacrifice. Thus there was a continual offering by fire unto the Lord; and hence in Lev 6:13 it is said: The fire shall ever be burning upon the altar, it shall never go out. If at any time any extraordinary offerings were to be made, the daily sacrifice was consumed more speedily, in order to make room for such extra offerings. See more on this subject in Clarke's note on Lev 6:23 (note). The Hebrew doctors teach that no sacrifice was ever offered in the morning before the morning sacrifice; and none, the passover excepted, ever offered in the evening after the evening sacrifice; for all sacrifices were made by day-light. The fat seems to have been chiefly burned in the night season, for the greater light and convenience of keeping the fire alive, which could not be so easily done in the night as in the day time.
Verse 11

And put on other garments - The priests approached the altar in their holiest garments; when carrying the ashes, etc., from the altar, they put on other garments, the holy garments being only used in the holy place.

Clean place - A place where no dead carcasses, dung, or filth of any kind was laid; for the ashes were holy, as being the remains of the offerings made by fire unto the Lord.
Verse 13

The fire shall ever be burning - See on Lev 6:9 (note) and Lev 6:20 (note). In imitation of this perpetual fire, the ancient Persian Magi, and their descendants the Parses, kept up a perpetual fire; the latter continue it to the present day. This is strictly enjoined in the Zend Avesta, which is a code of laws as sacred among them as the Pentateuch is among the Jews. A Sagnika Brahmin preserves the fire that was kindled at his investiture with the poita, and never suffers it to go out, using the same fire at his wedding and in all his burnt-offerings, till at length his body is burnt with it - Ward's Customs.
