Leviticus 6:16-18

16The priests will make into bread the flour that he did not burn. They must not use yeast to make the bread. They must eat the bread in a holy place, in the yard outside the Tent of Meeting.

17The bread is for the priests because it is a holy part of a gift. It is holy, like the offerings for sin. And it is like the gifts when somebody does anything wrong.

18Any son, grandson or male of Aaron's family can eat the bread. It is his usual part of the burnt offerings to the Lord. A person who touches the bread will become holy.’
