JERUSALEM — Israel’s postal service is delivering letters to a unique address that hasn’t changed in thousands of years. Ahead of the Jewish high holidays, it took some of the dozens of letters it receives each year that are addressed to God and delivered them to the Western Wall, where visitors traditionally place handwritten notes of prayer and wishes in the cracks between its stones. The postal service says the letters arrived from all over the world, including Russia, China, France, Nigeria and the United States.
