Final answer:
The Hebrew blessing for lighting candles on a holiday is 'Baruch ata Adonai, Eloheinu, melech ha'olam, asher kidshanu b'mitzvotav v'tzivanu l'hadlik ner shel [Shabbat/Yom Tov].' It is a prayer that honors the sanctity of the holiday by kindling the candles.
Step-by-step explanation:
The Hebrew blessing for lighting candles for a holiday, particularly on Shabbat or Jewish festivals such as Hanukkah, is called the Blessing of the Candles. The typical blessing recited during the lighting of candles on holidays is:
Baruch ata Adonai, Eloheinu, melech ha'olam,
asher kidshanu b'mitzvotav v'tzivanu l'hadlik ner
shel [Shabbat] [or shel Yom Tov, in the case of festivals].
This translates to: "Blessed are You, Lord our God, Sovereign of the universe, who has sanctified us with His commandments and commanded us to kindle the light of [Shabbat] [or the Holiday light, for festivals]." The blessing may vary slightly depending on the specific holiday.
