The prophet's words about vengeance on his enemies may seem an example of what is sometimes called "Old Testament vindictiveness." Yet Jeremiah has no intention of taking revenge. He merely hands his whole situation, completely and entirely, into God's hands. He understands perfectly: the work entrusted to him by God is not his work, but God's work. And he himself, Jeremiah, is only an instrument in this work, an executor from whom neither an assessment of the people involved nor, still less, punishment or vengeance upon them is required. The prophet must simply do his work: go where God sends him, say what He has instructed him to say, and leave the rest to Him.
But there are people around who hinder Jeremiah from doing God's work. This is an objective reality. One may treat the people who hinder him in any way one likes, but objectively they are enemies of God. This is not vindictiveness and not hatred; it is a simple statement of an obvious fact. It would be foolish to ignore the obvious, and the prophet does not try to do so: he turns to God for resolution of the situation.
His words about enemies are not evidence of hatred or a desire for vengeance in the human sense in which they are often interpreted. For God's vengeance is not like human vengeance, just as God's punishment is not human punishment. Human punishment is a sanction for violating a norm; human vengeance is evidence of triumph over an enemy. God's punishment, however, is only the triumph of His love over human sinfulness and the pain caused by sin that seeks to prevent this triumph; God's vengeance is the triumph of His will over those who oppose it and the fulfillment of His plans despite His opponents. It is not a desire to humiliate or suppress an enemy for the sake of His own triumph: God has no need to affirm Himself at the expense of a defeated opponent. He simply puts everything in its place, including those who oppose Him.
But God does not want their destruction. He wants these people to turn and receive the fullness of life that He can give them. And this desire of His becomes vengeance only for those who reject it. But that is no longer God's vengeance - it is a human choice.
