Texas prosecutors are done calling witnesses in the trial of a polygamist leader accused of sexually assaulting two girls he took as brides during so-called "spiritual marriages."

Prosecutors are expected Wednesday to rest their case against Warren Jeffs. The 55-year-old leads the Fundamental Church of Jesus Christ of Latter Day Saints, which believes polygamy brings exaltation in heaven. Followers consider Jeffs a profit.

On Tuesday, audio recordings seized by police were played that show Jeffs instructing a 14-year-old girl how to please him sexually. Prosecutors say Jeffs assaulted her when she was 15 and fathered her child.

Prosecutors have promised to play a tape of Jeffs having sex with the other alleged victim. She was 12.

Jeffs is representing himself and claims God will seek revenge if the trial continues.
