Imprecation against Terrorists

This is for the evil perpetrators of the Boston Marathon bombing: 

Let them be as chaff before the wind:

and let the angel of the Lord chase them.

Let their way be dark and slippery:

and let the angel of the Lord persecute them.

For without cause have they hid for me their net in a pit,

which without cause they dug for my soul.

Let destruction come upon him at unawares;

and let his net that he hath hid catch himself:

into that very destruction let him fall.

And my soul shall be joyful in the Lord:

it shall rejoice in his salvation.

     —Psalm 35:5-9
