• 7) me'il — a cloak of blue wool, with gold bells and pomegranates hanging from the bottom;

5- How are the Kohanim anointed?

• First, they have to stand outside of the mishkan with a bull that will be offered as a sacrifice.

• Moses will then put on Aaron his eight garments and pour some "anointing oil" on his head. 

• Then Aaron's sons will put on their clothing.

•                     They will then officially be Kohanim and can begin their service in the Mishkan.

•                                          From here on, all their children will be Kohanim forever. The last thing in the Parshah is instructions for how to build the golden altar.
