The document is a passage from the book of Malachi in the Bible. It discusses how the people of Israel had violated their covenant with God by being unfaithful to one another in their marriages and relationships. In particular, they had profaned the sanctuary of God by marrying foreign wives and adopting the practices of other nations, including divorce. The passage warns the people to remain faithful to their spouses and marriages, as God intended marriage to be a lifelong covenantal bond between a man, woman and God. It also criticizes the priests and leaders who had grown lax in their interpretation of the law to allow for divorce.
