Rashi on Exodus 29:23/רש"י על שמות כ״ט:כ״ג

1וככר לחם AND ONE LOAF OF BREAD — of the cakes (mentioned in Exodus 29:2) (Menachot 78a).

2וחלת לחם שמן AND ONE PIERCED CAKE OF OILED BREAD — of the “saturated" kind.

3ורקיק AND ONE WAFER — of the wafers there mentioned: i. e. one out of the ten which were comprised in each of these different kinds of bread (Menachot 76a; cf. Rashi on Exodus 29:2). We do not find that any heave-offering of bread brought with a sacrifice was burnt except this alone, for the heave-offering of the bread brought with the thanksgiving offering and with the ram of the Nazarite was given to the priest (and therefore not burnt) together with the breast and the shoulder, whilst of this the breast alone was given as a portion to Moses, as the officiating priest.
