Zechariah 5

In his sixth vision, Zechariah sees a Flying Scroll.  According to what is written on the scroll, the curse and consequent judgment of sin (symbolized by the breaking of 2 of the 10 commandents) is carried out "over the face of the whole earth."   This once again addresses Zechariah's initial message of the need for spiritual cleansing.

In the seventh vision, Zechariah sees a basket with a woman who represents wickedness.  The basket is taken to "Shinar" or "Babylon".  This again points to the cleansing of the "holy land" by the removal of wickedness.   This ultimately points to the End Times, when evil is defeated (ref. Revelation 17-18).

These visions are a reminder of the need for God's People to be holy and set apart.  This also is an encouragement, for we know that God is Just and all the evil in this world will ultimately be destroyed.
