Zohar on Tehillim 121 - Mezuzah
Tehillim 121:8
- «Adonai shomrecha, Adonai tzilcha al yad yeminecha» - (G-d will guard you when you enter and when you leave—always).
This is the secret of the mezuzah. The mitzvah of mezuzah is connected with the need for everyone who enters and leaves to be under the protection of the Almighty. The secret of the mezuzah is always revealed at the entrance to the home. This is the entrance of the higher Malchut into Zeir Anpin, the secret of the verse: «this is the entrance to the Almighty» (Tehillim 118:20), the level called «the Guarding Watchman».
(Zohar on Va'etchanan, Sulam, Zvi Nisan Zon)
Tehillim 118:20
- «Zeh hasha'ar La-Adonai - tzaddikim yavo'u vo» - (This is the entrance to the Almighty—let the righteous enter through it).
If a mezuzah is affixed at the entrance to a home, then when people enter it, the Yetzer Hara and that demon (which has permission to cause harm) guard it against their will and say: «this is the entrance to the Almighty—let the righteous enter through it.». But if there is no mezuzah at the entrance to the home, the Yetzer Hara and that demon grow stronger, join together, and place their hands on the person's head as he enters, saying: «Woe to this man; he has rebelled against his Master».
From that moment on, such a person is deprived of protection, and there is no one to guard him. May the Merciful Creator save us from this.
(Zohar on Va'etchanan, Sulam, Zvi Nisan Zon)
