Leviticus 21:3-5

Amplified Bible, Classic Edition

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.

⁵ The priests [like the other Israelite men] shall not shave the crown of their heads or clip off the corners of their beard or make any cuttings in their flesh.
