Jeremiah has been forbidden to pray for this people (verse 11), and yet he now prays for them again. How can we explain this? Was he simply ignoring what the Lord had said to him? Was this prayer an act of disobedience? That cannot be the case, for it is recorded in Scripture, and is here for us to learn from.
This too is a strong argument. Jeremiah is praying what the people ought to be praying, and his prayer is instruction in how to pray when we are in a desperate situation. The Lord Jesus said to the Samaritan woman, ‘Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs’ (Mark 7:27), but from this saying she spied a chink of hope. That word ‘first’ told her she could ask again, for she was coming to the embodiment of God’s mercy, and she was ready to do this, even though it meant humbling herself further. The backslider knows that there is no other road to recovery than to return to the God he has sinned against, and to make a full confession. He must be ready to wait in that place without moving, until the Lord responds. There is no one else he can go to, and no other source of healing, so he waits at the foot of the cross, resolved to stay there until either his life is ended, to the Lord answers.
