Leviticus 8:17 KJV

And he slew it; and Moses took the blood, and put it upon the horns of the altar round about with his finger, and purified the altar, and poured the blood at the bottom of the altar, and sanctified it, to make reconciliation upon it.

And he took all the fat that was upon the inwards, and the caul above the liver, and the two kidneys, and their fat, and Moses burned it upon the altar.

And he brought the ram for the burnt offering: and Aaron and his sons laid their hands upon the head of the ram.

And he killed it; and Moses sprinkled the blood upon the altar round about.
