Leviticus 21 · a question people ask
Couldn't the high priest even mourn his own father?
The verses name what he must not do. He "shall not let the hair of his head hang loose, or tear his clothes" (21:10), and "He must not go in to any dead body, or defile himself for his father or for his mother" (21:11). Moses had said the same to Aaron and his sons when Nadab and Abihu died: "Don’t let the hair of your heads go loose, and don’t tear your clothes", and "let your brothers, the whole house of Israel, bewail the burning" (Leviticus 10:6). Both times the anointing is the reason given for staying at the sanctuary. Then: "You shall not go out from the door of the Tent of Meeting, lest you die; for the anointing oil of the LORD is on you" (Leviticus 10:7). Here: "He shall not go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him" (21:12). The verses don't speak of what he felt. The other priests could defile themselves for their nearest relatives (21:2-3).
The verses
“except for his relatives that are near to him: for his mother, for his father, for his son, for his daughter, for his brother, and for his virgin sister who is near to him, who has had no husband; for her he may defile himself.”
““‘He who is the high priest among his brothers, upon whose head the anointing oil is poured, and who is consecrated to put on the garments, shall not let the hair of his head hang loose, or tear his clothes. He must not go in to any dead body, or defile himself for his father or for his mother. He shall not go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him. I am the LORD.”
“Moses said to Aaron, and to Eleazar and to Ithamar, his sons, “Don’t let the hair of your heads go loose, and don’t tear your clothes, so that you don’t die, and so that he will not be angry with all the congregation; but let your brothers, the whole house of Israel, bewail the burning which the LORD has kindled. You shall not go out from the door of the Tent of Meeting, lest you die; for the anointing oil of the LORD is on you.” They did according to the word of Moses.”
