Midrash sur Le Lévitique 8:21

18) "and Moses smoked the head, and the pieces, and the suet": as it is written (Vayikra 1:12): "And he shall cut it into its pieces, and its head and its suet." (Vayikra 8:21): "And the innards and the legs he washed with water": as it is written (Vayikra 1:13): "And the innards and the legs he shall wash with water." (Vayikra 8:21) "and Moses smoked the whole ram upon the altar": as it is written (Vayikra 1:13): "and he shall smoke it upon the altar." (Vayikra 8:21): "It is a burnt-offering for a sweet savor": as it is written (Vayikra 1:13): "a fire-offering, a sweet savor to the L–rd." From here it is derived that all (the limbs of the burnt-offering) are consigned to the fire.

Moses was first with the priesthood, with the pulpit, with the sacrifices, and with the Torah.
• [With the priesthood, when he served in the high priesthood for the seven days during the consecration (of Aaron and his sons.)]⁷³yYoma 1:1 (38b); Lev. R. 11:7; PRK 4:5; PR 14:11.
• With the pulpit, when he had Eleazar stand on the pulpit. Thus it is stated (in Numb. 3:32): AND THE PRINCE OF THE LEVITE PRINCES WAS ELEAZAR….⁷⁴As a Levite he would officiate from a pulpit.
• With the sacrifices: Where is it shown? (Lev. 8:21): MOSES SACRIFICED THE [WHOLE] RAM UPON THE ALTAR (during the consecration of Aaron and his sons).
• With the Torah: Where is it shown? Where it is stated (in Exod. 24:12): COME UP TO ME ON THE MOUNTAIN [AND BE THERE, AND I WILL GIVE YOU STONE TABLETS WITH TORAH AND THE COMMANDMENTS WHICH I HAVE WRITTEN FOR THEIR INSTRUCTION].
