On the altar he burned the fat, the kidneys, and the lobe of the liver from the sin offering, as the LORD had commanded Moses.

Commenting on Leviticus 9:8-22
But the fat, and the kidneys, and the caul above the liver of the sin offering, he burnt upon the altar,.... The Septuagint version is, "he offered them": as the Lord commanded Moses; see Lev 4:8.
But the fat, and the kidneys, and the caul above the liver of the sin offering, he burnt upon the altar; as the LORD commanded Moses. (e) That is, he laid them in order, and so they were burnt when the Lord sent down fire.
