Bull! (And a Ram)By Rabbi Jack Abramowitz
Moshe brought out the bull for the sin offering. Aharon and his sons placed their hands on the sacrifice, which Moshe then offered on their behalf. The fats and other relevant portions were burned on the altar and the rest was burned outside the camp.
Next, Moshe brought the ram for the burnt offering. Hands were laid upon the ram and Moshe offered it, too. The pieces were burnt on the altar after washing the legs and intestines. All this was done as G-d had instructed.
