From Psalm 37 (KJV)
The wicked plotteth against the just, and gnasheth upon him with his teeth. The Lord shall laugh at him: for he seeth that his day is coming. The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, and to slay such as be of upright conversation. Their sword shall enter into their own heart, and their bows shall be broken.
