Ezekiel 44:

Then the bronze man brought Ezekiel back to the gate of the sanctuary facing east, but it was shut.  God declared that the gate will remain shut because God has entered through it and no one must enter it.  The prince (son of the current king) is the only one allowed to enter and exit in the same direction.  God instructed Ezekiel to inform Israel that they must stay away from their detestable ways.  God banned the priest from serving at his sanctuary because they also served idols and were corrupt at taking illegal fees at the gate.  Only the family and descendants of Zadok, who were also Levites, were allowed in God’s sanctuary because they remain blameless towards God.  God then gave instructions on how priests are to dress and behave.  Priests must wear linen clothes and not wool, wear undergarment and not sweat, change clothes when they go out of the court to meet the people, their hair should not be long or should be shaved (trimmed), no alcohol during service (they can drink but not at work), not to marry divorced or widowed women, they may marry only Israeli virgins or widows of priests (so the Catholic church is wrong.  They need to marry and stop molesting young boys), priest should not deal with the dead unless it is a family member (afterwards cleanse himself, wait a week, and offer sin offering for himself), priest are to own nothing but God and enjoy the offering given to God (no other job) and the are not to eat dead animals.
