Leviticus 21:5-7

The Voice

⁵ Priests are not allowed to mourn like other people by shaving their heads, trimming their beards, or cutting gashes into their bodies. ⁶ Priests are to be holy to Me and not treat My sacred name with contempt. They bring the fire-offerings to Me, the food of their God, and so they must be sacred. ⁷ Priests are not to marry women defiled by prostitution or women who are divorced, for priests are holy to Me.
