Plony was the son of [[Miriam Magdalena]] and [[Joses Pantera]] the brother of [[Rebbe Yehoshuah Minzaret]].
He was nicknamed '''מסיח''' by the Ercolian Karaites.
He is admired in Karaite sources such as for example Judah Hadasi but his followers are criticized for abandoning him and changing his teachings to comply with Christian ideas.
