Negative Mitzvot 139, 112;
Positive Mitzvah 65

The Torah describes the service of each of the sacrifices, in detail.

Different types of sacrifices require different rites and procedures.

Some involve sprinkling the blood on the altar which stood in the courtyard of the Beit HaMikdash. Other sacrifices required the priest to sprinkle the blood on the altar which stood inside the sanctuary.

The sin offerings whose blood is sprinkled on the inside altar differ from others. Generally, the meat of the sin-offerings are divided; one part is eaten by the priests and one part is burnt on the altar.

However, the sin offerings whose blood is sprinkled on the inner altar are completely burnt. The priests are not allowed to eat from these offerings.

HaShem designed a special process for preparing a bird brought as a sin-offering.

Instead of slaughtering it with a knife, part of this procedure requires the priest to cut off the bird's flow of life from the back of its neck, by pinching or squeezing it.

This process is called "Melikah".

This Negative Mitzvah cautions the priest not to separate the bird's head from the rest of its body when he is preparing it for a sacrifice.

We are commanded to follow the procedures and rules detailed in the Torah for presenting a guilt offering.
