Ezekiel 41:2-4

2The entrance was ten cubits wide, and the projecting walls on each side of it were five cubits wide. He also measured the main hall; it was forty cubits long and twenty cubits wide.

3Then 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.

4And he measured the length of the inner sanctuary; it was twenty cubits, and its width was twenty cubits across the end of the main hall. He said to me, “This is the Most Holy Place.”
