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.
How the Ram of Consecration Taught the Laws of the Burnt-Offering
Sifra, Mekhilta deMiluim I 17
[יז] "ויקרב את איל העולה ויסמכו" – מכאן למדנו סמיכה לעולה. "וישחט ויזרק משה את הדם" – מכאן למדנו זריקה לעולה. "ואת האיל נתח לנתחיו" – כל המפורש בעולת יחיד מפורש כאן חוץ מהפשט; ויש אומרים אין נתוח בלא הפשט.
