Leviticus 22:22 "Nor (shall you) make an offering by fire of them upon the altar to the L-rd"

Certain parts of an animal that is sacrificed must be consumed by fire on the altar.

We are forbidden to place any portion of a blemished animal on the altar to be burned.

(It should be noted that the Negative Mitzvot mentioned in 91-94 deal with an animal that has permanent blemishes.)
