R. Eliezer b. Yaakov says: If you come to My house, I will come to your house. And if you do not come to My house, I will not come to your house. The place that My heart loves, there My feet will lead Me—whence they derived: Whenever ten men enter a synagogue, the Shechinah is with them, as it is written (Psalms 82:1) "G–d stands in the congregation of the Almighty." And whence is it derived (that the Shechinah reposes) even on three who judge? From (Ibid.) "In the midst of the judges, (three), does He judge." And whence is it derived (that it reposes) even with two? From (Malachi 3:16) "Then there conversed, the fearers of the L–rd, one to the other, and the L–rd listened, etc." And whence is it derived (that the same obtains) even with one? From "Wherever I shall mention My name I shall come to you and I shall bless you."
