Exodus 29:33-35

Lexham English Bible

³³ And they will eat them—the things by which atonement was made for them to ordain them to consecrate them—and a stranger will not eat them because they are holy objects. ³⁴ If any remains until morning from the ordination meat or from the bread, you will burn the remainder in fire; it will not be eaten, because it is a holy object. ³⁵ And you will do so for Aaron and for his sons, according to all that I have commanded you; seven days you will ordain them.
