Part 1 of 2בָּרוּךְ אַתָּה ה׳ אֱלֹקֵינוּ מֶלֶךְ הָעוֹלָם הַזָּן אֶת הָעוֹלָם כֻּלּוֹ בְּטוּבוֹ בְּחֵן בְּחֶסֶד וּבְרַחֲמִים הוּא נוֹתֵן לֶחֶם לְכָל בָּשָׂר כִּי לְעוֹלָם חַסְדּוֹ
Baruch Atah Adonai Elokeinu Melech ha'olam hazan et ha'olam kulo b'tuvo b'chen b'chesed uv'rachamim hu noten lechem l'chol basar ki l'olam chasdo
Blessed are You, Lord our God, King of the universe, who nourishes the entire world in His goodness — with grace, kindness, and mercy. He gives food to all flesh, for His kindness endures forever.
This is the opening of the first bracha (Birkat HaZan). The full Birkat Hamazon has 4 main brachot. Start by learning this opening — it captures the essence of the entire prayer.
Part 2 of 2וּבְטוּבוֹ הַגָּדוֹל תָּמִיד לֹא חָסַר לָנוּ וְאַל יֶחְסַר לָנוּ מָזוֹן לְעוֹלָם וָעֶד. בַּעֲבוּר שְׁמוֹ הַגָּדוֹל כִּי הוּא אֵל זָן וּמְפַרְנֵס לַכֹּל וּמֵטִיב לַכֹּל וּמֵכִין מָזוֹן לְכָל בְּרִיּוֹתָיו אֲשֶׁר בָּרָא. בָּרוּךְ אַתָּה ה׳ הַזָּן אֶת הַכֹּל
Uv'tuvo hagadol tamid lo chasar lanu v'al yechsar lanu mazon l'olam va'ed. Ba'avur sh'mo hagadol ki hu El zan um'farnes lakol umeitiv lakol umechin mazon l'chol b'riyotav asher bara. Baruch Atah Adonai hazan et hakol
Through His great goodness, we have never lacked food, and may we never lack it forever. For the sake of His great name, for He is God who feeds and sustains all, does good to all, and prepares food for all His creatures which He created. Blessed are You, Lord, who feeds all.
This completes the first bracha. The full Birkat Hamazon continues with three more brachot: thanks for the Land, request to rebuild Jerusalem, and general thanks for God's goodness.
