(13) Besides the cakes.--That is, the thirty un leavened cakes which were made of half of the quantity of the flour brought by the offerer, as described in the previous verse, the ten leavened cakes made of the other half of the flour are to be brought. These had all to be baked before the victim was slaughtered. The only other occasion when leavened bread formed part of the offering was on Pentecost (Leviticus 23:17); but no portion of it was burnt on the altar as a memorial, for leaven was forbidden to be on the altar. (See Leviticus 2:11-12.)

7:11-27 As to the peace-offerings, in the expression of their sense of mercy, God left them more at liberty, than in the expression of their sense of sin; that their sacrifices, being free-will offerings, might be the more acceptable, while, by obliging them to bring the sacrifices of atonement, God shows the necessity of the great Propitiation. The main reason why blood was forbidden of old, was because the Lord had appointed blood for an atonement. This use, being figurative, had its end in Christ, who by his death and blood-shedding caused the sacrifices to cease. Therefore this law is not now in force on believers.Besides the cakes,.... The unleavened cakes, and the unleavened wafers, and the fried cakes; or with these, as Aben Ezra and Abendana interpret it:

he shall offer for his offering leavened bread, with the sacrifice of thanksgiving of his peace offerings; not that this was offered upon the altar, for all leaven was forbidden there, Leviticus 2:11 but it was given to the priest, that he might have change of bread, and such as was agreeable to him, to eat with the flesh of the peace offerings he had a share of, and to the owners also; and the whole of this consisted of ten cakes likewise, as will appear by what Maimonides (g) says; he (the offerer) takes twenty tenths of fine flour, and makes ten leavened, and ten unleavened; the ten leavened he makes into ten cakes, and the ten unleavened he makes of them eighty cakes alike, ten cakes of every sort, ten cakes baked in an oven, ten cakes wafers, and ten cakes slightly baked.
