The people of Israel and Judah had gathered in Jerusalem to celebrate the Passover.  This great assembly rejoiced and praised God for being able to meet together once again.  And as their prayers rose to God, revival broke out.  For before they even traveled home, it says they went throughout the country-side smashing false idols, cutting down Asherah poles, and destroying other places of pagan worship.   Their prayers had been heard, they caught the vision God had for them, and they could not help but act on it.  I pray for the same type of revival to break out in us.
