Exodus 29:31

29“The holy garments of Aaron shall be for his sons after him, to be anointed in them, and to be consecrated in them.

30Seven days shall the son who is priest in his place put them on, when he comes into the Tent of Meeting to minister in the holy place.

31“You shall take the ram of consecration and boil its meat in a holy place.

32Aaron and his sons shall eat the meat of the ram, and the bread that is in the basket, at the door of the Tent of Meeting.

33They shall eat those things with which atonement was made, to consecrate and sanctify them; but a stranger shall not eat of it, because they are holy.
