We explained yesterday the declaration of the Prophet, -- that the kingdom would again be restored by the Lord, if the king and his servants and the whole people repented. He now introduces a commination, -- that if they heard not, it was all over with the palace and the city. But the word house, or palace is often repeated; for though the defenses of the city gave courage to the people, yet what made them especially proud was the confidence they felt that the kingdom had been promised to be for ever.

Hence he says, that God made an oath by himself; for it seemed incredible to the Jews, that the family which had been set apart by God from the world, would ever perish. It now follows:
