Hitherto we have had the instructions which Moses was directed to give to the people concerning the sacrifices; but here begin the instructions he was to give to the priests; he must command Aaron and his sons, Lev 6:9. The priests were rulers in the house of God, but these rulers must be ruled; and those that had the command of others must themselves be commanded. Let ministers remember that not only commissions, but commands, were given to Aaron and his sons, who must be in subjection to them.

In these verses we have the law of the burnt-offering, as far as it was the peculiar care of the priests. The daily sacrifice of a lamb, which was offered morning and evening for the whole congregation, is here chiefly referred to.

I.The priest must take care of the ashes of the burnt-offering, that they be decently disposed of, Lev 6:10, Lev 6:11. He must clear the altar of them every morning, and put them on the east side of the altar, which was furthest from the sanctuary; this he must do in his linen garment, which he always wore when he did any service at the altar; and then he must shift himself, and put on other garments, either such as were his common wear, or (as some think) other priestly garments less honourable, and must carry the ashes into a clean place without the camp. Now, 1. God would have this done, for the honour of his altar and the sacrifices that were burnt upon it. Even the ashes of the sacrifices must be preserved, to testify the regard God had to it; by the burnt-offering he was honoured, and therefore thus it was honoured, and therefore thus it was honoured. And some think that this care which was taken of the ashes of the sacrifice typified the burial of our Saviour; his dead body (the ashes of his sacrifice) was carefully laid up in a garden, in a new sepulchre, which was a clean place. It was also requisite that the altar should be kept as clean as might be; the fire upon it would burn the better, and it is decent in a house to have a clean fire-side. 2. God would have the priests themselves to keep it so, to teach them and us to stoop to the meanest services for the honour of God and of his altar. The priest himself must not only kindle the fire, but clean the hearth, and carry out the ashes. God's servants must think nothing below them but sin.

II.The priest must take care of the fire upon the altar, that it be kept always burning. This is much insisted on here (Lev 6:9, Lev 6:12), and this express law is given: The fire shall ever be burning upon the altar, it shall never go out, Lev 6:13. We may suppose that no day passed without some extraordinary sacrifices, which were always offered between the morning and evening lamb; so that from morning to night the fire on the altar was kept up of course. But to preserve it all night unto the morning (Lev 6:9) required some care. Those that keep good houses never let their kitchen fire go out; therefore God would thus give an instance of his good house-keeping. The first fire upon the altar came from heaven (Lev 9:24), so that by keeping that up continually with a constant supply of fuel all their sacrifices throughout all their generations might be said to be consumed with that fire from heaven, in token of God's acceptance. If, through carelessness, they should ever let it go out, they could not expect to have it so kindled again. Accordingly the Jews tell us that the fire never did go out upon the altar, till the captivity in Babylon. This is referred to Isa 31:9, where God is said to have his fire in Zion, and his furnace in Jerusalem. By this law we are taught to keep up in our minds a constant disposition to all acts of piety and devotion, an habitual affection to divine things, so as to be always ready to every good word and work. We must not only not quench the Spirit, but we must stir up the gift that is in us. Though we be not always sacrificing, yet we must keep the fire of holy love always burning; and thus we must pray always.

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.

And the priest shall put on his linen garment,.... "His measure" (q), as the word signifies, a garment that was just the measure of his body, and exactly fitted it; it was a sort of a shirt, which he wore next his body, and reached down to his feet; and in this he always officiated, and was an emblem of the purity and holiness of Christ our high priest, who was without sin, and so a fit person to take away the sin of others, by offering up himself without spot to God:

and his linen breeches shall he put upon his flesh; to cover his nakedness; that indecency might be prevented, and that he might not be exposed to ridicule; and though these two garments are only mentioned, yet the wise men say the word "put on" includes the bonnet and the girdle; for the removing of the ashes from the altar, which is the thing he was to be thus clothed to do, was done in the four garments, though the Scripture mentions but two (r):

and take up the ashes which the fire hath consumed, with the burnt offering on the altar; this was the first thing the priests did in a morning, and which in later times they cast lots for, and the first lot was for this service, and which was performed very early (s);"every day they cleansed or swept the altar, at cockcrowing or near it, whether before or after, and on the day of atonement at midnight, and at the feasts from the time of the first watch:"

and he shall put them beside the altar: without, at the corner of the altar, as Aben Ezra, on the east side of it; so says Jarchi, the priest takes a full censer of the innermost consumptions (that is, of the innermost parts of the sacrifice reduced to ashes), and puts them in the east of the rise of the altar; or, as by another (t) expressed, he takes the ashes in a censer, more or less, and lays them down at the east of the rise of the altar, and there leaves them, and this is the beginning of the morning service: and we are told by another writer (u), that there was a place called the house of ashes, and it was at the east of the rise of the altar, at a distance from the foot of it ten cubits and three hands' breadth; where the priest, before they began to sacrifice, laid the ashes of the sacrifices, and of the candlestick, and of the altar of incense, and of the offering of the fowl that were cast out.

THE LAW OF THE BURNT OFFERING. (Lev 6:8-13)

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 [Lev 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 [Lev 6:10-11], but the approaching near to the fireplace in garments that were not officially "holy."
