The title man of God, i. e., prophet, belongs to Hanan, identified by many with Hanani 2 Chronicles 16:7. The sons of Hanan were probably his disciples. If so, we find a religious school or sect, regularly established in the precincts of the temple, of whose views and modes of interpretation we know nothing. Plainly however, the Hananites were friendly to Jeremiah, and lent him their hall for his purpose.
The chamber of the princes - Probably the council-chamber in which the great officers of state met for the despatch of business.
The keeper of the door - There were three of these keepers, answering to the outer and inner courts of the temple, and the entrance to the temple itself. They were officers of high rank, having precedence next to the high priest and his deputy.
