While he was still fairly young, he was sent to Jerusalem to receive his education at the school of Gamaliel, one of the most noted teachers of Jewish law in history. Although modern scholarship agrees that Paul was educated under the supervision of Gamaliel in Jerusalem, he was not preparing to become a scholar of Jewish law, and probably never had any contact with the Hillelite school. Some of his family may have resided in Jerusalem since later the son of one of his sisters saved his life there. Nothing more is known of his biography until he takes an active part in the martyrdom of Stephen, a Hellenised diaspora Jew.
