6 "If you present an animal from the flock as a peace offering to the Lord, it may be a male or a female, but it must have no defects. 7 If you present a sheep as your offering, bring it to the Lord, 8 lay your hand on its head, and slaughter it in front of the Tabernacle. Aaron's sons will then splatter the sheep's blood against all sides of the altar. 9 The priest must present the fat of this peace offering as a special gift to the Lord . This includes the fat of the broad tail cut off near the backbone, all the fat around the internal organs, 10 the two kidneys and the fat around them near the loins, and the long lobe of the liver. These must be removed with the kidneys, 11 and the priest will burn them on the altar. It is a special gift of food presented to the Lord . 12 "If you present a goat as your offering, bring it to the Lord, 13 lay your hand on its head, and slaughter it in front of the Tabernacle. Aaron's sons will then splatter the goat's blood against all sides of the altar. 14 The priest must present part of this offering as a special gift to the Lord . This includes all the fat around the internal organs, 15 the two kidneys and the fat around them near the loins, and the long lobe of the liver. These must be removed with the kidneys, 16 and the priest will burn them on the altar. It is a special gift of food, a pleasing aroma to the Lord . All the fat belongs to the Lord . 17 "You must never eat any fat or blood. This is a permanent law for you, and it must be observed from generation to generation, wherever you live."

(Read Leviticus 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, Hebrews 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.
