Rashi on Leviticus 4:35/רש"י על ויקרא ד׳:ל״ה

1כאשר יוסר חלב הכבש [AND HE SHALL REMOVE ALL THE FAT THEREOF] AS THE FAT OF THE LAMB IS REMOVED — the fat portions of which have been augmented by the addition of the fat-tail (cf. v. 9): thus, too, does a sin-offering, whenever it is brought as she-lamb, require the fat-tail to be removed together with the other fat portions (cf. Sifra, Vayikra Dibbura d'Chovah, Chapter 11 4).

2על אשי ה׳ means upon the fire-pyres which are made for the Lord; foailles in O. F.
