I was helped in my preparation by these words of German theologian Erich Zenger:
'...the psalms of vengeance are a passionate clinging to God when everything really speaks against God. For that reason they can rightly be called psalms of zeal, to the extent that in them passion for God is aflame in the midst of ashes of doubt about God and despair over human beings. These psalms are the expression of a longing that evil, and evil people, may not have the last word in history, for this world and its history belong to God. Thus, to use the theological terminology, these psalms are realized theodicy. They affirm God by surrendering the last word to God. They give to God not only their lament about their desperate situation, but also the right to judge the originators of that situation. They leave everything in God's hands, even feelings of hated and aggression.
These psalms do not arise from the well-tempered psychological state of people from whom every scrap of sensitivity and emotion has been driven out. On the contrary, they are serious about the fundamental biblical conviction that in prayer we may say everything, literally everything, if only we say it to GOD, who is our father... We have, in the meantime, learned from psychology that suppressed fears and repressed aggression do not overcome violence, but multiply it. What is necessary is that we learn to live with fears and aggressions by bringing them to consciousness and acting against their destructiveness. The psalms do not repress all this; they express it before GOD and place it in GOD'S hands.'
