Leviticus 9:9-10

NHEB(i) 9 The sons of Aaron presented the blood to him; and he dipped his finger in the blood, and put it on the horns of the altar, and poured out the blood at the base of the altar: 10 but the fat, and the kidneys, and the cover from the liver of the sin offering, he burned upon the altar; as the LORD commanded Moses.
