3:16 Shall burn them - The parts mentioned, among which the tail is not one, as it was in the sheep. because that in goats is a refuse part. All the fat - This is to be limited, To those beasts, which were offered or offerable in sacrifice, as it is explained, Lev 7:23,25. To that kind of fat which is above - mentioned, and required to be offered, which was separated, or easily separable from the flesh for the fat which was here and there mixed with the flesh they might eat.
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.
