Directions are here given concerning the peace-offering, if it was a sheep or a goat. Turtle-doves or young pigeons, which might be brought for whole burnt offerings, were not allowed for peace-offerings, because they have no fat considerable enough to be burnt upon the altar; and they would be next to nothing if they were to be divided according to the law of the peace-offerings. The laws concerning a lamb or goat offered for a peace offering are much the same with those concerning a bullock, and little now occurs here; but, 1. The rump of the mutton was to be burnt with the fat of the inwards upon the altar, the whole rump (Lev 3:9), because in those countries it was very fat and large. Some observe from this that, be a thing ever so contemptible, God can make it honourable, by applying it to his service. Thus God is said to give more abundant honour to that part which lacked, Co1 12:23, Co1 12:24. 2. That which was burnt upon the altar is called the food of the offering, Lev 3:11, Lev 3:16. It fed the holy fire; it was acceptable to God as our food is to us; and since in the tabernacle God did, as it were, keep house among them, by the offerings on the altar he kept a good table, as Solomon in his court, Kg1 4:22, etc. 3. Here is a general rule laid down, that all the fat is the Lord's (Lev 3:16), and a law made thereupon, that they should eat neither fat nor blood, no, not in their private houses, Lev 3:17. (1.) As for the fat, it is not meant of that which is interlarded with the meat (that they might eat, Neh 8:10), but the fat of the inwards, the suet, which was always God's part out of the sacrificed beasts; and therefore they must not eat of it, no, not out of the beasts that they killed for their common use. Thus would God preserve the honour of that which was sacred to himself. They must not only not feed upon that fat which was to be the food of the altar, but not upon any like it, lest the table of the Lord (as the altar is called), if something were not reserved peculiar to it, should become contemptible, and the fruit thereof, even its meat, contemptible, Mal 1:7, Mal 1:12. (2.) The blood was universally forbidden likewise, for the same reason that the fat was, because it was God's part of every sacrifice. The heathen drank the blood of their sacrifices; hence we read of their drink-offerings of blood, Psa 16:4. But God would not permit the blood, that made atonement, to be used as a common thing (Heb 10:29), nor will he allow us, though we have the comfort of the atonement made, to assume to ourselves any share in the honour of making it. He that glories, let him glory in the Lord, and to his praise let all the blood be poured out.

The whole rump, it shall he take off hard by the backbone - To what has already been said on the tails of the eastern sheep, in the note on Exo 29:22, we may add the following observation from Dr. Russel concerning the sheep at Aleppo. "Their tails," says he, "are of a substance between fat and marrow, and are not eaten separately, but mixed with the lean meat in many of their dishes, and also often used instead of butter." He states also that a common sheep of this kind, without the head, fat, skin, and entrails, weighs from sixty to seventy English pounds, of which the tail usually weighs fifteen pounds and upwards; but that those of the largest breed, when fattened will weigh one hundred and fifty pounds, and their tails fifty, which corresponds with the account given by Ludolf in the note referred to above. The sheep about Jerusalem are the same with those in Abyssinia mentioned by Ludolf, and those of Syria mentioned by Dr. Russel.

And he shall offer of the sacrifice of the peace offering,.... That is, the priest, Aaron, or one of his two sons:

an offering made by fire unto the Lord; that part of it which was to be burnt with fire; and in the peace offering of the lamb there was something more than in the peace offering of the bullock, or of the goat, which follows:

the fat thereof, and the whole rump, it shall he take off hard by the backbone; not the rump or tail, but the fat of it; the copulative "and" is not in the text; wherefore Aben Ezra says, that Gaon was mistaken in reading it as we do, "the fat there of", and "the whole rump"; but it should be rendered, "its fat of the whole rump", or "tail": in the eastern countries (k), some sheep and lambs had very large tails, and very fat ones, the least weighing ten or twelve pounds, the largest above forty, and were put in little carts for ease and safety; see Gill on Exo 29:22 now such as were "whole", entire, perfect, and without blemish, as the word signifies, the fat of them that was next to the backbone was to be taken off of such as were brought for peace offerings:

and the fat that covereth the inwards, and all the fat that is upon the inwards; as before; See Gill on Lev 3:3.

the two kidneys . . . of the flock . . . the whole rump--There is, in Eastern countries, a species of sheep the tails of which are not less than four feet and a half in length. These tails are of a substance between fat and marrow. A sheep of this kind weighs sixty or seventy English pounds weight, of which the tail usually weighs fifteen pounds and upwards. This species is by far the most numerous in Arabia, Syria, and Palestine, and, forming probably a large portion in the flocks of the Israelites, it seems to have been the kind that usually bled on the Jewish altars. The extraordinary size and deliciousness of their tails give additional importance to this law. To command by an express law the tail of a certain sheep to be offered in sacrifice to God, might well surprise us; but the wonder ceases, when we are told of those broad-tailed Eastern sheep, and of the extreme delicacy of that part which was so particularly specified in the statute [PAXTON].
