Leviticus 21:3

or his unmarried sister who is near to him, since she has no husband.

And for his sister a virgin, that is nigh unto him, which hath had no husband; for her may he be defiled.

and for his virgin sister who is near to him, who has had no husband; for her he may defile himself.

and for his sister a virgin, that is near unto him, that hath had no husband; for her may he defile himself.
