Jamaal Michael Barrow aka Shyne is legally changing his name to Moses Michael Leviy due to his loyal following of Judaism.
The Belize-born MC converted to Judaism while serving his jail sentence and even claims to be descended from the Ethiopian Jews.
Shyne hopes to be released from the upstate Clinton Correctional Facility next year.
According to the NY Daily News, Shyne also plans to have his attorney on Tuesday challenge the state's so-called Son of Sam law, which bars jailbirds from profiting from their crimes.
"He was the sole support of his family," said attorney Oscar Michelen. "They're in very difficult financial circumstances."
Barrow and his lawyer are hoping that a Brooklyn Supreme Court justice will allow the rapper's mom to dig into a $500,000 advance from a five-album deal the performer signed with Island Def Jam in March 2004.
Barrow's assets - including royalties from his 2004 album, "Godfather Buried Alive" - are frozen until civil lawsuits filed against him by three wounded clubgoers are resolved.
