Leviticus 21:3

A Conservative Version

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

See the chapter Copy

except for his kin, who is near to him: for his mother, and for his father, and for his son, and for his daughter, and for his brother.

He shall not defile himself, [who is] a chief man among his people, to profane himself.

And if a priest's daughter be married to a stranger, she shall not eat of the heave-offering of the holy things.
