Their widows — The prophet still speaks of things to come as if present. In Jehoiakim's time we read of no such plenty of widows; they were multiplied when the city was besieged and taken in Zedekiah's time, to a great number, hyperbolically compared to the sands of the sea. The mother — Jerusalem was the mother of the Jewish people, against whom, Nebuchadnezzar the spoiler, at noon — day, was sent.
