Thematic Bible: Specially required to avoid

And Yahweh said unto Moses, Say unto the priests, the sons of Aaron, - yea thou shalt say unto them, For a dead person, shall no one make himself unclean among his people: Saving for his kin, that are near unto him, for his mother or for his father, or for his son or for his daughter, or for his brother; or for his sister, a virgin who is near unto him, who belongeth not unto a husband, - for her, he may make himself unclean: read more.
He shall not make himself unclean being a chief among his people, - by profaning himself: They shall not make a baldness behind in their head, And the border of their beard, shall they not cut off, - And, in their flesh, shall they not make incisions. Holy persons, shall they be unto their God, and not profane the name of their God, - for, the altar-flames of Yahweh, the food of their God, do they bring near - Therefore shall they be holy.

And, unto no persons b of the dead, shall he go in, - For his father or for his mother, shall he not make himself unclean; And, out of the sanctuary, shall he not go forth, so shall he not profane the sanctuary of his God, - for the consecration of the anointing oil of his God is upon him - I, am Yahweh.
