New Defender's Study Bible Notes
3:1 peace offering. The “peace offering,” offered usually as an expression of thankfulness, symbolized peace between the offerer and God. The animal was to be eaten on the same day as it was sacrificed (Leviticus 7:15-16; 22:29-30).
3:2 blood upon the altar. Deuteronomy 12:27 says that the blood “shall be poured out upon the altar.” A part of the sacrificial blood was sprinkled on the altar, the remainder poured out at its base (note Deuteronomy 12:24).
3:3 all the fat. The fat was considered the best part of the animal, and so belonged to God. Neither the fat nor blood was to be included in the part of the offering to be eaten (note Genesis 9:4).
3:5 upon the burnt-sacrifice. The burnt offerings were kept burning continually (Exodus 29:38); hence the peace offerings had to be laid on the burnt offering on the altar.
