III. His appeal to God hereupon, v. 20. His eye is to God as the Lord of hosts, that judges righteously. It is a matter of comfort to us, when men deal unjustly with us, that we have a God to go to who does and will plead the cause of injured innocency and appear against the injurious. God's justice, which is a terror to the wicked, is a comfort to the godly. His eye is towards him as the God that tries the reins and the heart, that perfectly sees what is in man, what are his thoughts and intents. He knew the integrity that was in Jeremiah's heart, and that he was not the man they represented him to be. He knew the wickedness that was in their hearts, though ever so cunningly concealed and disguised. Now, 1. Jeremiah prays judgment against them: "Let me see thy vengeance on them, that is, do justice between me and them in such a way as thou pleasest." Some think there was something of human frailty in this prayer; at least Christ has taught us another lesson, both by precept and by pattern, which is to pray for our persecutors. Others think it comes from a pure zeal for the glory of God and a pious and prophetic indignation against men that were by profession priests, the Lord's ministers, and yet were so desperately wicked as to fly out against one that did them no harm, merely for the service he did to God. This petition was a prediction that he should see God's vengeance on them. 2. He refers his cause entirely to the judgment of God: "Unto thee have I revealed my cause; to thee I have committed it, not desiring nor expecting to interest any other in it." Note, It is our comfort, when we are wronged, that we have a God to commit our cause to, and our duty to commit it to him, with a resolution to acquiesce in his definitive sentence, to subscribe, and not prescribe, to him.
