A Jewish home is traditionally marked by a mezuzah (parchment scroll containing Torah verses) on each door, outer and inner, that is not a door to a bathroom. These scrolls must be hung in their ceremonial cases within thirty days of moving into a house, and frequently a party is held in order to accomplish this ritual task.
Several weeks after we moved into our new home, we invited friends over on Saturday night for a hanukat bayit (dedication of the home) -- a housewarming. We began the evening with havdalah (the blessing over the end of the Sabbath), but at the conclusion of havdalah, before dousing the braided candle that traditionally accompanies the blessing, we used it to light 10 smaller tapers. These candles were then passed out to groups of people along with a mezuzah, a hammer and nail (or appropriate tools) and the location of a door where that mezuzah would hang. (Drilling of holes and marking of mezuzah locations were done beforehand.) Together we recited the appropriate blessings:
בָּרוּךְ אַתָּה אֲדֹנָי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם אֲשֶׁר קִדְּשָׁנוּ בְּמִצְוֹתָיו וְצִוָּנוּ לִקְבֹּעַ מְזוּזָה
Barukh ata adonay eloheynu melekh haolam asher kidshanu bemitzvotav vetzivanu likboah mezuzah
בְּרוּכָה אַתְּ יָהּ אֱלֹהֵינוּ רוּחַ הָעוֹלָם אֲשֶׁר קִדַשְׁתַנוּ בְּמִצְוֹתֵיהָ וְצִוְתָנוּ לִקְבֹּעַ מְזוּזָה
Brukha at yah eloheynu ruakh haolam asher kidshatnu bemitzvoteha vetzivatnu likboah mezuzah
Blessed are you, God, Sovereign/Spirit of the Universe, who has sanctified us with God's commandments and commanded us to affix the mezuzah.
בָּרוּךְ אַתָּה אֲדֹנָי אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, שֶׁהֶחֱיָנוּ וְקִיְּמָנוּ וְהִגִּיעָנוּ לַזְּמָן הַזֶּה
Barukh ata adonay eloheynu melekh haolam shehekheyanu vekiymanu vehigianu lazman hazeh
בְּרוּכָה אַתְּ יָהּ אֱלֹהֵינוּ רוּחַ הָעוֹלָם שֶׁהֶחֱיָתְנוּ וְקִיְּמָתְנוּ וְהִגִּיעָתְנוּ לַזְּמָן הַזֶּה
Brukha at yah eloheynu ruakh haolam shehekhiyatnu vekiymatnu vehigiatnu lazman hazeh
Blessed are you, God, Sovereign/Spirit of the Universe, who has given us life, sustained us, and enabled us to reach this joyous time.
Then we dispersed throughout the house in the dark to affix our mezuzot on various doorposts. It felt magical and mysterious as our guests scattered and the lights twinkled throughout the darkened house. Only when all the mezuzot were hung did we turn on the lights and put out the candles.
We liked the idea of carrying the sweetness of Shabbat not only into the week but into the physical corners and doorposts of the house, by using the havdalah candle to light the other lights.
A traditional prayer for the home to use during this ceremony:
Within these gates
Let there come
Within this dwelling
Let there come
Through these doors
Let there come
With this family unit
Let there be
Within this place
Let there be only
Blessing and Peace
