In November of 1999, Gadi completed a commission of a twenty-eight foot wall designed for the Sefardic community in Mexico City. The community wanted to create a wall that would be an alternative to the ordinary "Tree of Life" that is commonly seen in synagogues. The wall is comprised of 1700 letters each cut, cast in sand, and polished individually by hand in Massachusetts and flown to Mexico City.  

The "Wall of Blessing" mural of text taken from the last chapter of Deuteronomy, in which Moses blesses the tribes of Israel before his death stands inside the entrance hall to the exquisite new synagogue in the Lomas section of Mexico City. Each family in the community sponsored one letter. The donor¹s name appears on the wall beneath their letter.

A lithograph was presented to each family with the last chapter of the book of Deuteronomy written in both Spanish and Hebrew with an embossed metalpiece replicating their letter on the wall.
