Exodus 29:23-25

Darby Translation

²³ and one loaf of bread, and one cake of oiled bread, and one wafer out of the basket of the unleavened [bread] that is before Jehovah;

²⁴ and thou shalt put all this in the hands of Aaron, and in the hands of his sons, and shalt wave them as a wave-offering before Jehovah.

²⁵ And thou shalt receive them of their hand and burn [them] upon the altar over the burnt-offering, for a sweet odour before Jehovah: it is an offering by fire to Jehovah.
