Blessings

Before mezuzahs are mounted, the traditional blessing is said:

Blessed are You, Lord our God, King of the Universe, who has sanctified us with his commandments, commanding us to affix the mezuzah.

Some also say the Shehechyanu:

Blessed are You, Lord our God, King of the Universe, who has kept us alive and sustained us and permitted us to reach this moment.

Traditionally, salt and bread are then brought into the home and blessed, symbolizing that there never be a lack of food in the house.
