Charles Ellicott Commentary 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." — Zechariah 5:2 (ASV)

He. —The angel-interpreter. (Compare to Zechariah 5:5.)

The length ... and the breadth ... —These were the dimensions of the holy place of the Mosaic Tabernacle, also of the porch of Solomon’s Temple. If, then, we are to consider the measurement of the scroll as symbolical, we may regard it as indicating that the measure of the sanctuary is the measure of sin: that is, the sinner must not say, “I am not worse than my neighbour,” but should measure his conduct by the standard: Become ye holy, for I am holy (Leviticus 11:44).
