Ezekiel 41:2-5
2 The entrance was ten cubits wide, and the projecting walls on each side of it were five cubits wide. He also measured the outer sanctuary; it was forty cubits long and twenty cubits wide.
3 Then he went into the inner sanctuary and measured the jambs of the entrance; each was two cubits wide. The entrance was six cubits wide, and the projecting walls on each side of it were seven cubits wide.
4 And he measured the length of the inner sanctuary; it was twenty cubits, and its width was twenty cubits across the end of the outer sanctuary. He said to me, “This is the Most Holy Place.”
5 Then he measured the wall of the temple; it was six cubits thick, and each side room around the temple was four cubits wide.
