Leviticus 6:9

Verse Leviticus 6:9. 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 Leviticus 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 "Leviticus 6:23".

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 conveniency of keeping the fire alive, which could not be so easily done in the night as in the day time.
