Leviticus 21:2-4

Amplified Bible, Classic Edition

² Except for his near [blood] kin, for his mother, father, son, daughter, brother,

³ And for his sister, a virgin, who is near to him because she has had no husband; for her he may be defiled.

⁴ He shall not even defile himself, being a [bereaved] husband [his wife not being his blood kin] or being a chief man among his people, and so profane himself.
