Leviticus 6:15-16

15The priest on duty will take from the grain offering a handful of the choice flour moistened with olive oil, together with all the frankincense. He will burn this representative portion on the altar as a pleasing aroma to the Lord.

16Aaron and his sons may eat the rest of the flour, but it must be baked without yeast and eaten in a sacred place within the courtyard of the Tabernacle.
