We now perceive for what purpose the Prophet, after having addressed the captives, turned his discourse to King Zedekiah and to the Jews, who as yet remained at home or in their own country; it was, that the captives might hence know how great was their madness to promise to themselves a return, after having been driven to remote lands, when final ruin was nigh both the king and the people, who as yet remained at Jerusalem; Thus then saith Jehovah to the king who sits on the throne of David, and to all the people who sit in this city, etc
To sit, as I have already said, is to be taken here in two different senses; the king is said to sit on his throne while he retains his dignity; but the people are said to sit while they rest and dwell quietly in any place. It is not without reason that the word king is here expressly mentioned, for the exiles were ever wont to connect it with the hope of their return; “The Temple still remains, God is there worshipped, and the kingdom still exists; these things being secure, it cannot be all over with our nation.” The safety of the people depended on the kingdom and the priesthood. When therefore, on the one hand, they fixed their eyes on royalty, and on the other hand, on the priesthood and sacrifices, they felt persuaded that it could not be otherwise but that God would soon restore them; for God had promised that the kingdom of David would be perpetual, as long as the sun and moon would shine in heaven. Except then this splendor or glory had been extinguished, the Israelites could not have been humiliated, especially as those who had been led into exile were of the tribe of Judah. We now understand why the word king was expressly mentioned. Though, then, a king still sat on the throne of David, he yet declares that his condition and that of his people was harder than that of the captive multitude.
