Ezekiel 44:20-22

American Standard Version

²⁰ Neither shall they shave their heads, nor suffer their locks to grow long; they shall only cut off the hair of their heads. ²¹ Neither shall any of the priests drink wine, when they enter into the inner court. ²² Neither shall they take for their wives a widow, nor her that is put away; but they shall take virgins of the seed of the house of Israel, or a widow that is the widow of a priest.
