He prohibited us from offering frankincense in the offering of a sinner. And that is His, may He be exalted, saying, "neither shall he put any frankincense upon it" (Leviticus 5:11). And one who placed [it] is lashed. And the language of the Mishnah (Menachot 59b) is, "He is liable for the oil on its own, and for the frankincense on its own" - since they are two [distinct] negative commandments, without a doubt. And the regulations of this commandment have already been explained in the fifth [chapter] of Menachot. (See Parashat Vayikra; Mishneh Torah, Sacrificial Procedure 12.)
