Ezekiel 44:25

And they shall not go in to the dead body of a man to defile themselves: only [a priest] may defile himself for a father, or for a mother, or for a son, or for a daughter, or for a brother, or for his sister, who has not been married.

And they shall not go in to the dead body of a man to defile themselves: only [a priest] may defile himself for a father, or for a mother, or for a son, or for a daughter, or for a brother, or for his sister, who has not been married.

And they shall come at no dead person to defile themselves: but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may defile themselves.
