"Let a thousand fall from your side." Rabbi Yitzhak said, "The hand that controls one mitzvah, namely the tefillin of the arm, has been given a thousand angels. But the right hand, which controls many mitzvot, has been given myriad angels. Rabbi Chanina bar Abba said that it does not say 'given,' but 'fallen,' because if a thousand destructive forces come before the left hand, they fall before it, and if a myriad come before the right, they fall before it, because it controls many mitzvot.
In the custom of the world, if a person is given a thousand people to feed, they are entrusted to him for his benefit and protection. But God entrusted this person with a thousand angels on his left and myriad on his right to protect him, and yet he is not supported, and nevertheless, he will not approach you. Only in Your eyes will he look, for You, God, are his refuge. Rabbi Chanina said, "My soul is from the blue [sky] and my eyes from the green [grass].
You gave the Torah to the lower world and the upper world rejoices in Your dwelling place. No harm will come near you. Rabbi Yochanan said, "Before the Mishkan was established, the destructive forces would harm people. When the Mishkan was established, no harm came near your tent.
This is the Mishkan. Another explanation is that Reish Lakish said, "From whom do we learn from the book of Psalms? We learn from its location (in Bamidbar 6:24), 'May God bless you and keep you.' He will keep you from all evil.
When? On the day that the Mishkan was established." (Reish Lakish said that it is in the book of Psalms, 'May God bless you from the destructive forces.' When? On the day that Moses finished building the Mishkan.)"...
