'King of Israel' in the Bible

The words of Amos, who was among the herdsmen of Tekoa; the Word which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash king of Israel, two years before the earthquake.

Then Amaziah the priest of Bethel sent to Jeroboam king of Israel, saying, Amos has plotted against you in the midst of the house of Israel; the land is not able to bear all his words.
