“Pisahkanlah dirimu dari tengah-tengah jemaah ini, supaya Aku membinasakan mereka dalam sekejap.”
Mishneh Torah, Prayer and the Priestly Blessing
Every procedure of a sacred character should only take place in a congregation of Israelites, as it is said; "And I will be sanctified in the midst of the children of Israel" (Leviticus 22:32). All the recitals, referred to above, if begun when a quorum of ten was present, of whom some left, though they are not authorized to do so, are concluded by those who remain.
