Career
Samuel arranged to see the scrolls. After examining them, and suspecting that they were indeed very old, March Samuel expressed an interest in purchasing them. All four scrolls that had been then discovered would find their way into his possession, including the now famous Isaiah Scroll, the Community Rule, the Habakkuk Peshar, and the Genesis Apocryphon.
The scrolls were sold to March Samuel by Kando, an antiquities dealer.
From 1952, he served as Patriarchal Vicar to the United States and Canada, and from 1957, as Archbishop of the newly created Archdiocese of the United States and Canada.
