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 week through the valley of darkness. For he is truly his brothers' keeper and the finder of lost children, and I will strike down upon thee with great vengeance and furious anger those who atempt to poison and destroy my brothers and you will know that my name is the Lord when I lay my vengeance upon thee.
