Then he is to remove all the fat, just as it is removed from the peace offering, and the priest is to burn it on the altar as a pleasing aroma to the LORD. In this way the priest will make atonement for him, and he will be forgiven.
Jewish Publication Society of America Version (JPS1917) - Leviticus 4:31 >And all the fat thereof shall he take away, as the fat is taken away from off the sacrifice of peace-offerings; and the priest shall make it smoke upon the altar for a sweet savour unto the LORD; and the priest shall make atonement for him, and he shall be forgiven.
