Zechariah 5:1 Meaning

1Then I turned, and lifted up mine eyes, and looked, and behold a flying roll.

2And 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.

3Then said he unto me, This is the curse that goeth forth over the face of the whole earth: for every one that stealeth shall be cut off as on this side according to it; and every one that sweareth shall be cut off as on that side according to it.
