Albert Barnes Commentary Leviticus 8:2

"Take Aaron and his sons with him, and the garments, and the anointing oil, and the bullock of the sin-offering, and the two rams, and the basket of unleavened bread;" — Leviticus 8:2 (ASV)

A bullock ... two rams ... a basket - compare Exodus 29:1-3. This shows the coherence of this part of Leviticus with the latter part of Exodus. The basket of unleavened bread used on this occasion appears to have contained:

1. cakes or loaves of the ordinary unleavened bread;
2. cakes of oiled bread, rather, oil bread (see Leviticus 2:1, Leviticus 2:4); and
3. oiled wafers (see Leviticus 2:4, Leviticus 2:6).

Rabbinical tradition says that there were six cakes of each sort.
