On Affixing a Mezzuza
Before affixing a Mezzuza say the following:
Barukh atah Adonai, Eloheinu, melekh ha’olam
Blessed are you, Lord, our God, sovereign of the universe
asher kidishanu b’mitz’votav v’tzivanu lik’bo’a m’zuzah
Who has sanctified us with His commandments and commanded us to affix a mezuzah
The mezuzah should then be affixed to the upper third of the doorpost on the right side as one enters the house or room. If the doorpost is wide enough to permit, the mezuzah should be tilted with the upper part slanting inward toward the house or room.
