Levítico 8:19 Midrash: Sifra

17) (Vayikra 8:18) "And he presented the ram of the burnt-offering, and Aaron and his sons placed their hands on the head of the ram.": From here we derive the requirement of semichah for a burnt-offering. (Vayikra 8:19): "And he slaughtered, and Moses sprinkled the blood upon the altar roundabout.": From here we derive the requirement of sprinkling for a burnt-offering. (Vayikra 8:20): "And he cut the ram into its pieces": Everything stated explicitly about an individual burnt-offering is stated here, except flaying. And some say there is no cutting into pieces without flaying.
