Before kindling the Chanukah lights on the first night of Chanukah, Saturday night, December 8 2012, (or if you're kindling the Chanukah lights for the first time this year) recite all three blessings. On every subsequent night only the first two are recited.
Recited only on the first night (or the first time lighting this Chanukah):
1. Ba-ruch A-tah Ado-nai E-lo-he-nu Me-lech ha-olam a-sher ki-de-sha-nu be-mitz-vo-tav ve-tzi-va-nu le-had-lik ner Cha-nu-kah.
2. Ba-ruch A-tah Ado-nai E-lo-he-nu Me-lech Ha-olam she-a-sa ni-sim la-avo-te-nu ba-ya-mim ha-hem bi-zman ha-zeh.
3. Ba-ruch A-tah Ado-nai E-lo-he-nu Me-lech Ha-olam she-heche-ya-nu ve-ki-yi-ma-nu ve-higi-a-nu liz-man ha-zeh.
1. Blessed are You, Lord our G-d, King of the universe, who has sanctified us with His commandments, and commanded us to kindle the Chanukah light.
2. Blessed are You, Lord our G-d, King of the universe, who performed miracles for our forefathers in those days, at this time.
3. Blessed are You, Lord our G-d, King of the universe, who has granted us life, sustained us, and enabled us to reach this occasion.
