Êxodo 29
23And one loaf of bread, and one cake of oiled bread, and one wafer out of the basket of the unleavened bread that is before the LORD :
28And it shall be Aaron’s and his sons’ by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the LORD .
