(16) Shall burn them.--That is, the fat pieces which have thus been specified (see Leviticus 4:35), because they constitute the bread of Jehovah; they are to ascend in a sweet-smelling savour to heaven. (See Leviticus 1:9).

All the fat is the Lord's.--This part of the verse is intimately connected with the following verse. As the fat belongs to the Lord, it is therefore enacted as a perpetual statute that it must never be eaten.

3:6-17 Here is a law that they should eat neither fat nor blood. As for the fat, it means the fat of the inwards, the suet. The blood was forbidden for the same reason; because it was God's part of every sacrifice. 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 claim for ourselves any share in the honour of making it. This taught the Jews to observe distinction between common and sacred things; it kept them separate from idolaters. It would impress them more deeply with the belief of some important mystery in the shedding of the blood and the burning the fat of their solemn sacrifices. Christ, as the Prince of peace, made peace with the blood of his cross. Through him the believer is reconciled to God; and having the peace of God in his heart, he is disposed to follow peace with all men. May the Lord multiply grace, mercy, and peace, to all who desire to bear the Christian character.And the priest shall burn them upon the altar,.... Which shows that not the fat only, but the inwards and the kidneys, were burnt also; so Maimonides says (l), that the priest salted the parts, and burned them upon the altar; and the priests might not have the breast and shoulder (which were what belonged to them) until the parts were burnt:

it is the food of the offering made by fire; which the Lord ate of, or accepted of:

for a sweet savour; as a type of the sweet smelling sacrifice of Christ, with which he is well pleased:

all the fat is the Lord's; that is, all that was upon the parts mentioned in the several sacrifices of peace offerings, which was to be taken off and burnt: though the Jewish writers understand it of all fat in general, and so interpret the law that follows.
