Some believe that these words from verse 14 to the end belong before verse 11. That is not to say that they have been misplaced, but that this is the way the prophet, or the one who records this passage for him, works.
Absolutely nothing that we are called to go through is as bad as this. There have been those among God's servants, like inspired prophets, who were put through such abasement before they saw the hand of God. Nothing like that has happened to us. The prophets are examples of the most severe suffering, so that those who come after them, can look back and be sure that they will be delivered.
We are not told what God did about this – how he reproved Jeremiah, or what these complaints led to, or what personal comfort Jeremiah was given on this occasion to lift him out of this very low state and condition. Of course, we can understand his collapse. It does prompt us to think about the treachery of the people around him, the scheming and the plotting of all his associate priests, the hatred and the lies told about him, and other sufferings which are not recorded which no doubt he suffered. But the effect upon him is to depress him immensely. But what we are told in the very next chapter, is that he was given – not only as a comfort, but as a serious ministry – something exceptionally different from anything that he had known.
