But God will shoot them with arrows; suddenly they will be struck down.  He will run their own tongues against them and bring them to ruin; all who see them will shake their heads in scorn.  All mankind will fear; they will proclaim the works of God and ponder what he has done.  Let the righteous rejoice in the Lord and take refuge in him; let all the upright in heart praise him!

The moral of this story is: the wicked can plot and scheme and plan, but God is in charge and they are not getting away with anything.  In the end, it is God Who will triumph.  Can there be any safer place than refuge in Him?
