Ezekiel 42:16-20

The man measured the east side with the measuring stick; it was eight hundred seventy-five feet by the measuring stick. He measured the north side; it was eight hundred seventy-five feet by the measuring stick. He measured the south side; it was eight hundred seventy-five feet by the measuring stick. He went around to the west side; it measured eight hundred seventy-five feet by the measuring stick. So he measured the Temple area on all four sides. The Temple area had a wall all around it that was eight hundred seventy-five feet long and eight hundred seventy-five feet wide. It separated what was holy from that which was not holy.
