Claim: On returning home and ascending the throne on the death of his father, Izates discovered the conversion of his mother who had never won over to Judaism.
Evidence: Izates II (Greek: Ἰζάτης, Hebrew: זוטוס בן מונבז‎; ca. 1-54 CE) was king of the Parthian client kingdom of Adiabene from approximately 30 to 54. His mother had been previously won over to Judaism without his knowledge. On returning home and ascending the throne on the death of his father (c. 31 CE), Izates discovered the conversion of his mother; and he himself intended to adopt Judaism, and even to submit to circumcision.
