Exodus 29:23-25

Complete Jewish Bible

²³ along with one loaf of bread, one cake of oiled bread and one wafer from the basket of matzah which is before Adonai — ²⁴ and put it all in the hands of Aharon and his sons. They are to wave them as a wave offering in the presence of Adonai. ²⁵ Then take them back; and burn them up in smoke on the altar, on top of the burnt offering, to be a pleasing aroma before Adonai; it is an offering made to Adonai by fire.
