I have some Psalms for this occasion.
>The heathen are sunk down in the pit that they made: in the net which they hid is their own foot taken.
>The LORD is known by the judgment which he executeth: the wicked is snared in the work of his own hands. Higgaion. Selah.
>The wicked shall be turned into hell, and all the nations that forget God.
Psalm 9:15-17
>Blessed is the man whom thou chastenest, O LORD, and teachest him out of thy law;
>That thou mayest give him rest from the days of adversity, until the pit be digged for the wicked.
Psalm 94:12-13
