sweet savour. This is added here because of the burning of the fat. It is not said of the sin offering of the high priest, the ruler, or the congregation (compare verses: Leviticus 4:10; Leviticus 4:19; Leviticus 4:26), though used in the burnt offerings (Leviticus 1:9; Leviticus 1:13), and peace offerings (Leviticus 3:5; Leviticus 3:16). The sweet savour here, in this connection, exalts the offering of the humblest person.

31 And he shall take away all the fat thereof, as the fat is taken away from off the sacrifice of peace offerings; and the priest shall burn it upon the altar for a sweet savour unto the LORD; and the priest shall make an atonement for him, and it shall be forgiven him.
