Prayer and Religious Articles: Prayer and Blessings: A Minyan:
What is the source for requiring ten men
(a "minyan") for certain religious services?
Ten men are required for reciting prayers in
which G-d's name is sanctified (Megillah 23b),
such as the Kaddish or Kedushah. This is
derived from the verse "I will be sanctified
among the Children of Israel" (Lev. 22:32),
and from the fact that in Gen. 42:5, Jacob's
ten sons (excluding Joseph and Benjamin) are
referred to as "the Children of Israel".
