John Gill Commentary Leviticus 8:26

"and out of the basket of unleavened bread, that was before Jehovah, he took one unleavened cake, and one cake of oiled bread, and one wafer, and placed them on the fat, and upon the right thigh:" — Leviticus 8:26 (ASV)

And out of the basket of unleavened bread
Moses was ordered to take, (Leviticus 8:2) ,

that [was] before the Lord ;
being brought to the tabernacle, where now the Lord had taken up his residence:

he took one unleavened cake ;
which had no oil in it or upon it:

and a cake of oiled bread ;
which was mixed and tempered with oil:

and one wafer ;
which was anointed with oil:

and put them upon the fat, and upon the right shoulder ;
of the ram of consecration, which he took from it, and laid the cakes uppermost upon them.
