John Wesley on Leviticus 21:12

Out of the sanctuary - To attend the funerals of any person: for upon other occasions he might and did commonly go out. Nor profane the sanctuary - Either by the performance of a civility, or by entering into the sanctuary before the seven days allotted for his cleansing, Num 19:11, were expired. The crown of the anointing oil - Or, the crown, the golden plate, which is called the holy crown, Exo 29:6, and the anointing oil of his God are upon him. So there is only an ellipsis of the conjunction and, which is frequent. And these two things, being most eminent, are put for the rest, as the sign is put for the thing signified, that is, for he is God's high - priest.
