Numbers 6:15

And a basket of unleavened bread
As at the consecration of Aaron and his sons, ( Exodus 29:2 ) ; though for peace offerings for thanksgiving leavened bread was offered, ( Leviticus 7:13 ) ;

cakes of fine flour mingled with oil, and wafers of unleavened bread
anointed with oil;
ten of each sort, as Jarchi says, ten cakes and ten wafers, see ( Exodus 29:9 ) ( Leviticus 7:12 ) ;

and their meat offering and their drink offering;
which always used to attend every sacrifice.
