Birkas Hamazon From Hashem's Hand

The center of the bracha of Racheim is occupied with a list of personal requests beginning with “Elokeinu, avinu, re’einu.” They contain the wish that Hashem sustain us with His “full, open, holy and generous Hand.” This distinguishes the gift from on high from the gift of human hands, which is often insufficient, may be granted through favoritism, and may have been acquired by unethical means. The bracha then flows into a prayer for Jerusalem: Uvnei Yerushalayim. It emphasizes that Hashem will rebuild Jerusalem b’rachamav, with mercy.
