Adam Clarke on Jeremiah 33:1

Moreover the word of the Lord - This was in the eleventh year of the reign of Zedekiah, Jeremiah being still shut up in prison: but he was now in the court of the prison, where the elders and the king's officers, etc., might consult him with the greater ease; for they continued to inquire, foolishly thinking, that if he would but prophesy good things, that these must come, or that he had sufficient power with God to induce him to alter his mind, - destroy the Chaldeans, and deliver the city.
