Salt Lake City , Utah ( CNN ) -- The estranged wife of the man accused of kidnapping then-14-year-old Elizabeth Smart from her family 's Salt Lake City home in 2002 testified Friday that the defendant manipulated her into doing things by saying his orders were divine law . `` I was told that no matter how difficult I found the load to bear , I needed to follow the law or suffer eternal consequences , '' said Wanda Barzee about her husband , Brian Mitchell . Mitchell played to his wife 's strong religious beliefs , telling her that divine revelations required she carry out acts that included participating in the kidnapping , she said in her second and final day of testimony in her husband 's trial . `` I was told that we were commanded to take 14-year-old young women and we were to snatch them out of the world and train them up in the ministries of God , '' said Barzee . She is serving a sentence of up to 15 years after striking a plea deal last year with state and federal prosecutors for her role in the abduction and agreeing to testify for the prosecution . But the prosecution did not call her , the defense did . Mitchell used the revelations to explain his heavy drinking , his engaging in oral sex with Smart and his demand that she `` demonstrate sexual activity '' in front of Smart , said Mitchell . `` He never expressed any remorse about kidnapping Ms. Smart , did he ? '' Prosecutor Francis Viti asked . `` No , '' Barzee responded . Barzee said she helped Mitchell in his meticulous preparation for Smart 's abduction , from setting up the bucket that the girl was to use as her bathroom to setting up the tent in which the girl was to be raped . `` I was told that I needed to listen to the plan of my husband , '' she said . Asked if that meant she `` needed to be submissive and obey ? '' Barzee responded , `` Yes . '' Mitchell told her prior to the Smart abduction `` that I needed to take seven wives into my heart and home , '' Barzee said , adding that the news upset her greatly . One such attempt involved a fellow church member named Kelly who was eight months pregnant with another man 's child , said Barzee , who added that she agreed to Kelly becoming another wife to Mitchell . Mitchell ultimately ended the marriage with Kelly for reasons that Barzee said were unclear . An attempt to recruit a shoe store worker named Julie to become one of Mitchell 's wives failed , she said . During the winter of 2001 , Mitchell revealed a new divine order , Barzee said . `` We were given the commandment to take young girls , between the ages of 10 to 14 years old . '' Mitchell would go downtown to `` minister , '' which she said meant to beg , `` and stalk young girls out -- try to find out where they lived . '' On June 4 , 2002 , the night of the abduction , she and Mitchell fought , Barzee said . `` I just knew how drastically my life was going to change , '' she said , adding that she was `` devastated '' by the prospect of taking the girl by force . Barzee , who had taken medication for mental illness prior to marrying Mitchell , said she stopped taking it when they were together at his insistence . She said her biggest fear was losing Mitchell and that she was terrified of being alone . Barzee wept when recounting having been forced by Mitchell to cook her 10-year-old daughter 's pet rabbit and serve it to her . `` Brian had me tell her that it was chicken , '' said the mother of six from a previous marriage . Barzee 's testimony came after her husband was escorted from the courtroom after he began singing hymns , as he has been doing throughout the trial . Mitchell faces life in prison if he is convicted of kidnapping and transporting a minor across state lines for sexual purposes . Barzee is being held at a federal medical center in Fort Worth , Texas , where she has been receiving mental health treatment , including medication .
Wanda Barzee says she regrets having succumbed to her husband 's demands . Brian Mitchell played to her strong religious beliefs , estranged wife says . Witness says she was ordered to cook her daughter 's pet rabbit , then serve it to her .
