Exodus 29:30; Exodus 29:35; Exodus 29:37
The son who succeeds him as priest and comes to the Tent of Meeting to minister in the Holy Place is to wear them seven days.
"Do for Aaron and his sons everything I have commanded you, taking seven days to ordain them.
For seven days make atonement for the altar and consecrate it. Then the altar will be most holy, and whatever touches it will be holy.
