Ezekiel 41:3-4

Then the man went inside and measured the side walls of the next doorway. Each was three and one-half feet thick. The doorway was ten and one-half feet wide, and the walls next to it were each more than twelve feet thick. Then the man measured the room at the end of the Holy Place. It was thirty-five feet long and thirty-five feet wide. The man said to me, “This is the Most Holy Place.”
