Chart of the Prophets of Israel and Judah

God raised up certain "prophets" who were His mouthpieces. They would speak out against their sin and idolatry and would continually warn of God's judgment. Some of the prophets spoke out in the North and some in the South, but God was faithfully warning them of certain catastrophe if they would not turn to him.
