Ezekiel 40:5

Now behold there was a wall on the outside of the temple all around; and the man had in his hand a reed of six cubits long by the cubit and hand breadth, so he measured the outer wall. The breadth equalled the reed and its height was equal to the reed.

And behold a wall round about the house without, and in the man's hand a reed, the measure of it was six cubits by the cubit, and a span: and he measured across the front wall; the breadth was equal to the reed, and the length of it equal to the reed.
