In orthodox Judaism, a minyan – a quorum of ten Jewish males who have undergone initiation (Bar Mitzvah) – is required in order to hold a full worship service, including the public Torah reading, the priestly benediction, and the recitation of the prayer known as Kaddish (chanted, for example, by mourners). A biblical sentence, "God stands in the divine assembly" (Psalms 82:1) led the ancient rabbis to comment that if ten men pray together, God's presence (His shekhinah) hovers over them. (Avot 3.6).
