Zechariah 5:2

And he said unto me, What seest thou? And I answered, I see a flying roll; the length thereof is twenty cubits, and the breadth thereof ten cubits.

I see a flying roll; the length thereof is twenty cubits, and the breadth thereof ten cubits - 30 feet by 15, the dimensions of the temple porch (1 Kings 6:3), where the law was usually read, showing that it was divinely authoritative in the theocracy. Its large size implies the great number of the curses contained. The Hebrew [ mªgilaah (H4039)] for "roll" or 'volume' is used of the law (Psalms 40:7).
