C. F. Keil and Franz Delitzsch on Leviticus 7:13-14

Lev 7:13-14

This sacrificial gift the offerer was to present upon, or along with, cakes of leavened bread (round, leavened bread-cakes), and to offer “thereof one out of the whole oblation,” namely, one cake of each of the three kinds mentioned in Lev 7:12, as a heave-offering for Jehovah, which was to fall to the priest who sprinkled the blood of the peace-offering. According to Lev 2:9, an azcarah of the unleavened pastry was burned upon the altar, although this is not specially mentioned here any more than at Lev 7:9 and Lev 7:10; whereas none of the leavened bread-cake was placed upon the altar (Lev 2:12), but it was simply used as bread for the sacrificial meal. There is nothing here to suggest an allusion to the custom of offering unleavened sacrificial cakes upon a plate of leavened dough, as J. D. Michaelis, Winer, and others suppose.
