Ezekiel 44:22-24

Amplified Bible

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. ²³ The priests shall teach My people the difference between the holy and the common, and teach them to distinguish between the (ceremonially) unclean and the clean. ²⁴ In a controversy they shall take their stand to act as judges; they shall judge it in accordance with My ordinances. They shall also keep My laws and My statutes in all My appointed feasts and sanctify My Sabbaths.
