The blessing that is done at the end of a meal when we start by breaking bread at the beginning with the blessing of Hamotzie.
The first blessing on the bread that we say before we start the meal:
בָּרוּךְ אַתָּה ה’, אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם הַמּוֹצִיא לֶחֶם מִן הָאָרֶץ.
Blessed are You, Lord our God, King of the Universe, who brings forth bread from the ground.
