et le surplus de l’oblation sera pour Aaron et ses fils, comme éminemment sainte entre les sacrifices du Seigneur.
Tosefta Yoma
How does the High Priest "take a portion ahead [of the other Kohanim]" (see Yoma 1:2)? He says, "This is my sin-offering" or "This is is my guilt-offering," [or] "One of the two loaves [is mine]," [or] "Four or five loaves from the showbread [is mine]." Rebbi says, I say, he can retain half for himself, as it is said (Lev. 2:3), "And what is left over from the grain-offering is for Aaron and his sons," that [the portion for] Aaron would be weighed against [the portion for] his sons. In what case does this apply? With holy things of the Temple, but as to holy things of the outlying areas, whether one is the High Priest or an ordinary Kohen, their portions are divided equally.
