Ezekiel 44:20-22

New Catholic Bible

²⁰ Priests are not permitted to shave their heads or to let their hair grow long. Rather, they must keep their hair carefully trimmed, ²¹ nor are they allowed to drink wine on the day they are to enter the inner court.

²² Priests may not marry either widows or divorced women, but only virgins of the race of Israel. However, they may marry women who are the widows of priests.
