Salt Lake City ? Just three months before Elizabeth Smart disappeared, the man suspected of kidnapping her declared himself a messenger of God and said it was God’s will that true followers live with multiple wives.

In a rambling 27-page tract typed out on a computer a year ago, Brian David Mitchell had a special word for his wife: “Thou wilt take into thy heart and home seven sisters, and thou wilt recognize them through the spirit as thy dearest and choicest friends from all eternity.”

He goes on to prophesy that his wife will take on “seven times seven sisters, to love and care for; forty-nine precious jewels in thy crown.” But she will remain the “jubilee of them all, first and last.”

Mitchell’s wife, Wanda Barzee, is not referred to by name in the text but is called Hephizibah Eladah Isaiah, which translates to “God Adorneth,” one of her nicknames on the street.

Authorities are expected to charge Mitchell, 49, and Barzee, 57, as early as Monday with kidnapping Elizabeth last June.

Brian David Mitchell walks in Salt Lake City in the spring of 2002. Mitchell is being held in connection with last June's kidnapping of Elizabeth Smart.

The manifesto is in the hands of authorities, who are trying to figure out whether “sisters” is a euphemism for “wives” and whether the declarations have anything to do with Smart’s disappearance.

It offers a look into Mitchell’s mindset in the months before Smart’s disappearance. Calling his tract “The Book of Immanuel David Isaiah,” Mitchell writes as if he is a direct conduit from God.

In an entry dated March 2002, Mitchell explains his justification for polygamy: The people of the church have forgotten the “law of consecration,” a Mormon teaching that calls on people to pool their belongings and live communally, and God has punished them by commanding them to have “one wife only” — a “lesser blessing.”

But because God is just and merciful, those who truly follow him can reclaim the blessing of multiple wives — God’s true intention, Mitchell writes.
