Ezekiel 44:20-22

Amplified Bible

²⁰ Also they shall not shave their heads, yet they shall not allow their hair to grow long; they shall only cut short or trim their hair. ²¹ Nor shall any priest drink wine when he enters the inner courtyard. ²² And they shall not marry a widow or a divorced woman; but they shall marry virgins of the descendants of the house of Israel, or a widow who was previously married to a priest.
