God raised up the prophet Jonah, and by him declared the purposes of his favour to Israel. It is a sign that God has not cast off his people, if he continues faithful ministers among them. Two reasons are given why God blessed them with those victories: 1. Because the distress was very great, which made them objects of his compassion. 2. Because the decree was not yet gone forth for their destruction. Many prophets there had been in Israel, but none left prophecies in writing till this age, and their prophecies are part of the Bible. Hosea began to prophesy in the reign of this Jeroboam. At the same time Amos prophesied; soon after Micah, then Isaiah, in the days of Ahaz and Hezekiah. Thus God, in the darkest and most degenerate ages of the church, raised up some to be burning and shining lights in it; to their own age, by their preaching and living, and a few by their writings, to reflect light upon us in the last times.
