A b'rakhah is a blessing, from the root barakh, which also carries the picture of kneeling. But hear the direction of it, because the direction is everything. A Hebrew blessing always moves upward, to the Giver, never downward onto the thing. The blessing said over bread at every Jewish table is barukh atah Adonai... hamotzi lechem min ha'aretz, Blessed are You, YHWH, who brings forth bread from the earth. It blesses HaShem for the bread. It does not bless the bread.

That single grammatical fact quietly undoes a great deal of later theology. You cannot bless an object into holiness; you bless the One who gave it, and your gratitude rises to Him. When the accounts of the last meal say Yeshua took bread and blessed, every Jew in the room knew He was thanking the Father, not consecrating the loaf. The b'rakhah is the gratitude going up, not power coming down.
