Joash

Jeroboam II

Jehoram

Jeroboam

He suggests the reign of Joash and the ministry of Jehoiada. during the reign of Jeroboam II Jonah ministered Israel. Joel predicted the outpouring and ministry of the Holy Spirit upon the earth. He probably lived in Jerusalim at the time. Israel enjoyed material prosperity and worshiped golden calves. The poor were oppressed by the rich and the leaders were corrupt. They trusted in their own strength and power.
