The king of Babylon (as appears from 2 Kings 25:1 Jeremiah 39:1) besieged Jerusalem in the tenth month of the ninth year of Zedekiah, so as he had besieged it some time before the revelation of this prophecy came to Jeremiah. Jeremiah was at that time a prisoner, in a prison within the king's house. The king could keep him from revealing God's will to the people, but he could not keep God from revealing himself to him. Prisons hinder us from communion with men, but often contribute to God's people freer and sweeter communion with him. In the mean time the desperate hardness of this prince and these people's hearts appear, in that the fear of an enemy besieging them could not awe them from such outrageous acts of persecution.
