132. Rabbi Aba continued, It is written, "Hashem shall preserve your going out and your coming in from this time forth, and forevermore" (Tehilim 121:8). HE ASKS, "Preserve your going out" is correct, but what is meant by, "your coming in"? For whoever enters his house is not afraid AND NEEDS NOT BE KEPT. HE ANSWERS, The man who places the holy mark in his house with the words of the Supernal Name, NAMELY THE MEZUZAH, is protected from everything. When that man goes out of his apartment to the gate of his house, he lifts up his eyes, sees the holy mark and looks at the gate. When he leaves, it escorts and guards him. When that man enters, it pronounced before him, Take care of the honor of the King's image. All this because of that mark of the Holy Name that is marked on his door.
133. Not only is a man kept in his house, the Holy One, blessed be He, keeps him when he comes in and goes out, as it is written, "Hashem shall preserve your going out and your coming in." Happy are Yisrael in this world and in the World to Come.
134. Come and see, woe to the man who does not know how to beware of the evil spirit that lies between the doorposts, and does not mark the gate to his house with a holy Supernal Name, NAMELY THE MEZUZAH, to be with him. For that evil spirit has 365 evil prosecuting officers IN THE 365 DAYS OF THE YEAR; each serves on its day. They are all present with him, WITH THAT MAN, throughout the days of the year and denounce him above and below. They are all with him day and night. They prosecute him by day and by night distress him in his dreams.
135. When it is about to denounce him when he enters HIS HOUSE, they put their hands on his shoulders and say to him, Woe to so-and-so who left his Master's domain. Woe to so-and-so in this world and in the World to Come. For that reason the faithful should be marked in every way, marked with their Master's imprint, NAMELY WITH THE PRECEPT, so every aspect of evil species shall fear them and so they will be kept in this world and in the World to Come. Happy is the lot of Yisrael. It is written of them, "Your people also shall be all righteous. They shall inherit the land forever" (Yeshayah 60:21).
