There's a passage I got memorized,
seems appropriate for this situation:
Ezekiel 25:17. "The path of the
righteous man is beset on all sides
by the inequities of the selfish and
the tyranny of evil men. Blessed is
he who, in the name of charity and
good will, shepherds the weak through
the valley of darkness, for he is
truly his brother's keeper and the
finder of lost children. And I will
strike down upon thee with great
vengeance and furious anger those
who attempt to poison and destroy my brothers. And you will know my name is the Lord when I lay my vengeance upon you."
