Reply To: Chidushim on Daf Yomi

ברכות מו,א

The Rabbenu Bechaye in Parshes Teruma Shmos (25,24) on וציפת אתו זהב טהור you should cover the table with pure gold the word זהב is זן, הארץ and בונה ירושלים. It could be that the three brochos of bentching is biblical but Moshe Rabbenu, Yehoshua and David Hamelech instituted the nusach of each. The Ramban explains the meaning of whoever lives in chutz laaretz is like worshiping a’z. There are seventy rulers above on each nation and Hashem kaveyochol rules over Eretz Yisroel, so these are intermidiaries but our provision comes thtough Eretz Yisroel. Maybe that is why the second brocho is the rememberance of the land and the third the redemption the rebuilding of malchus and the Beis Bamikdash.
My Rebbe the Mattersdorfer Rav, Rav Shmuel ztz’l said that we should always have ‘pure gold’ earned honestly.
