Exodus 29:29-33

29“The holy garments that belong to Aaron are to belong to his sons after him, so that they may be anointed in them and consecrated in them.

30The priest who succeeds him from his sons, when he first comes to the tent of meeting to minister in the Holy Place, is to wear them for seven days.

31“You are to take the ram of the consecration and cook its meat in a holy place.

32Aaron and his sons are to eat the meat of the ram and the bread that was in the basket at the entrance of the tent of meeting.

33They are to eat those things by which atonement was made to consecrate and to set them apart, but no one else may eat them, for they are holy.
