From the Mosaic work of Jonathan Mandell: The image is based on the Bet Alpha Synagogue floor in Israel. The Hebrew inscription reads "Brit Milah." This refers to the ritual circumcision in the Covenant Gd made with Abraham. The hand of Gd is made from abalone, hematite and pyrite. The ram is ceramic tile with turetella agate as his coat. His eye and horn (shofar) are abalone. The tree to which he is tied is ceramic tile and glass gems. Abraham's sword is mirror and it's handle is tigereye. Isaac's eyes are chrysicolla. To the right is the sacrificial altar.
