Mishnah for Numbers 14:49

Rabbi Halafta of Kefar Hanania said: when ten sit together and occupy themselves with Torah, the Shechinah abides among them, as it is said: “God stands in the congregation of God” (Psalm 82:1). How do we know that the same is true even of five? As it is said: “This band of His He has established on earth” (Amos 9:6). How do we know that the same is true even of three? As it is said: “In the midst of the judges He judges” (Psalm 82:1) How do we know that the same is true even of two? As it is said: “Then they that fear the Lord spoke one with another, and the Lord hearkened, and heard” (Malachi 3:16). How do we know that the same is true even of one? As it is said: “In every place where I cause my name to be mentioned I will come unto you and bless you” (Exodus 20:21).

Rabbi Shimon ben Elazar said: Do not try to appease your friend during his hour of anger; Nor comfort him at the hour while his dead still lies before him; Nor question him at the hour of his vow; Nor strive to see him in the hour of his disgrace.

Ten miracles were wrought for our ancestors in Egypt, and ten at the sea. Ten plagues did the Holy one, blessed be He, bring upon the Egyptians in Egypt and ten at the sea. [With] ten trials did our ancestors try God, blessed be He, in the Wilderness, as it is said, “and they have tried Me these ten times and they have not listened to my voice” (Numbers 14:22).
